Re: Acid
 

One told me right at my start in Stock: "STOCK IS NOT STOCK!!" :eek::D

Re: Acid
 

With the allowance of aftermarket cylinder heads, better valves, any valve job/angle, and tooling marks in the throat no need for it.

Re: Acid
 

Back in the 80's we used it on a circle dirt track motor, we never got caught using it.

Plus I tripped a little on it back in the 70's LOL

Re: Acid
 

Back in the day when they started to let super stock port, some cars went the same others went faster. Some Pro Stock cars were fast and winning races and then went slow. Some racers work there butts off spending time and money and effort, one will take short cuts to go fast, but they are all called cheaters. There are so many well respected racers on this site and to slam them when you come on here just to try to stir stuff up with your no name rants, it will not get or garner any respect for yourself.

Re: Acid
 

Is that what you consider yourself? a purist?

Re: Acid
 

Can i get my money back on the rulebook I bought , it’s pretty clear on heads, but apparently everyone gets upset to ask a real question , the one joker said I slammed somebody , I don’t know where he came up with that conclusion , best regards , no wonder we can’t get any new one in the sport, imo,

Re: Acid
 

Listen 'Toon, if you are interested in a set of heads, why not contact
someone who has a reputation for building Fast Stocker Heads.
You come on here with a no-name handle, wanting information
that may or may not be available, and if it is available, I imagine like
most work on precision racing engine, it would be expensive. Then,
after asking questions where you want possible free information,
hiding behind a Cartoon, you slam people for not playing your game.
You say you have a rulebook, good. Now go build yourself a Stocker.

Re: Acid
 

Show me where i slammed someone?, according to the rulebook , you can’t do anything to the heads, so i got plenty , why so angry , no wonder people don’t but their name on here !show me where i got out of line with the good ol boy club ?

Re: Acid
 

So it seems to me that if you can't or won't "acid" a set of heads then build a combo which won't respond to "acided" heads. As long as NHRA is not going to respond to them, people are going to use them!

Re: Acid
 

I see other ones on here getting crucified for cheating and not following the rulebook , then almost everyone says ignore the section on stock heads , , thanks for not ripping me a new one like some are trying to do , lol ,

Re: Acid
 

Quit acting like a victim here. Plenty have asked legit questions that are straightforward and show interest in the sport and most get helpful responses . Your cute introduction attracted the attention and responses you should have expected.

I think it was best said in a few other responses. There are people who push the rules and they are out there in every sport.

Come out from behind the Bubski and introduce yourself. If you truly are interested in building a car, ask questions that can be answered, not statistics that no one could answer.

Re: Acid
 

No victim here , ive calculated the answers,, 97+% are doped, even though rulebook says they can’t be touched # nhra3%stock,they probably shouldn’t say anything about a transbrake or delay box , but thats where they draw the line , lol, best regards , , is bubski really that busy ?

Re: Acid
 

Well mr. Schaechter !! You've summoned Bubski thrice and down the rabbit hole goes Bubski !! Bubski willl now give a little 411 to the OP of this thread !! Now please have some courtesy and taste !! Bubski has all the equipment at hand to do this and is typing from that perspective !! Get yourself some good cores , do the guides and a close to finish valve job !! "close to finish" means about flat in the chamber on a SBC head , now get out that DIAMOND CUT burr and blend in the valve job and the entire head , leave no stock casting !! get some flow numbers and proceed to work the bowl and short turn to the best you can within the lift limits imposed by the rules of valve lift and .150 after maximum lift !! if possible without hurting low lift !! Now shot blast those things real good and paint the ports with a heavy coat of cast blast paint , now finish the valve job !! its gonna look real outta place with those shiny angles in the blasted and painted port and that is good !! Now CC and mill the heads to spec !! Chop off as much as you need on the intake side, short of goin thru the valve cover bolt holes to get it to spec , same with exhaust !! You must leave a little casting between ports to be legal !! Don't just mill it all flat you shouldn't have too !! Now paint all the oil exposed parts of the head , under valve cover , bottom of head etc with a heavy coat of Glyptal paint and paint the rest of the head your engine color of choice heavily !! Why !! You don't want any easily identifiable factory casting texture to be seen !! They will only see what you give them to see now !! NO ACID on heads !! Bubski realizes this is an oversimplification of what it takes and apologizes for any left out info or steps !! NHRA is only interested in numbers period !! There is no this doesn't like right anymore !! Its a shame but that's the way it is and that's why Bubski chooses SS !! CHEERS !! back to the 85b to finish some intake flanges !!

Re: Acid
 

What happens when and if they (NHRA) cleans the intake runners with a solvent that attacks the intake runner paint?

Re: Acid
 

Ya know, just a couple of ignorant observations; as per the Stock rules under Cylinder Heads, "any film coating of intake or exhaust runners" is prohibited. Isn't paint a "film" coating? Also per the Stock rules under Cylinder Heads, "must retain original valve sizes at original angles +/- 1 degree". Just how far are you "milling" that head and at how much of an angle? Not fer nuthin' but if you're angle "milling" that head the usual .125 then you're moving that "angle" more than 1 degree!

Re: Acid
 

According to one gentleman’s retort, nhra caught on along time ago and now you can do anything as long as runners cc ok, his words , not mine , not sure i quite followed bubski milling technically, appears you would have a fun time getting the intake angle milled correctly, ive got several sets bone stock untouched sets of ,double hump heads if tech forgot what they should look like , one set has been milled and tapped for screw in studs for the rockers, , all runners original, best regards

Re: Acid
 

Tunemastah

It would be funny as hell if you show up with these heads get pulled for tear down and get bounced for modified heads!! LOL!! :eek::D

Ya think this has happened in the past! LOL!

Re: Acid
 

Well Frank, I'm sure that you've heard the story about my car getting tossed at Indy because my heads looked "too stock"!

Re: Acid
 

Just a dumb question here....
Why paint the intake runners?

Re: Acid
 

Everyone knows that porting has been going on in Stock for decades. I'm sure some have even welded ports and chambers.

With the valve job rule and availability of CNC seat and guide machines, like a Newen, I don't see the point of porting and risk being tossed. In most cases, camshaft lift is 0.550" and under. Getting heads to work without porting is not impossible, so long as you're willing to do the R&D or pay for it.

Re: Acid
 

Apparently the hackers are trying to hide all the illegal work ,, #rulebookwhatever

Re: Acid
 

#toonbegone

Re: Acid
 

LOL!
What initially came to mind was mid 2000s E-town national was spectating walked up to the tear down area. Ran into Dave Mitchell he was running the white wagon back then. He luckily was pulled for random tear down and got bounced for heads that didn't look right. They were untouched bone stock guess like yours were toooooo stock looking.......

Opened my eyes to reality........ :eek::D

Re: Acid
 

Good morning to all,
With regards to "painting" or "film " in the intake runners, reminds me of a story from NASCAR that they didn't allow cylinder head porting at the time. Some of the talented engine builders used to Paint the intake runners with either Clear Lacquer or Clear Enamel spray paint to help the "flow" without grinding in the ports. When racing against other "stock heads" there was a slight performance advantage, but eventually that practice was not allowed. Now I'm not going to drag my Father into this hornets nest , but he used to say " there's more then one way to skin a cat"!
So with the talented engine builders and racers we have today , all that is in the past and with the technology that's available to us today - if you work hard enough , you should be able to reach your goals .
Good luck on your endeavors.

Respectfully,
Henry Kunz 1534 H/SA

Google "Smokey Yunick Slurry" for some interesting reading!

The actual race was the easy part!

Re: Acid
 

This is a great read. I enjoyed it.

Re: Acid
 

I can neither confirm or deny 🤪

Re: Acid
 

Every one knows, some ofthe really fast cars do not just have light weight spools, gears and ceramic wheel bearings.

Plus you can't really go out now and buy 10 sets of 455 Oldsmobile heads and have them flowed to find the best two.

Re: Acid
 

Without reading thru all the threads, which acid is best?

Re: Acid
 

Lmao

Re: Acid
 

Without reading thru all the threads, which acid is best? I have found that white vinegar works best. Just buy a couple gallons pour it into a bucket and put rusty parts, bolts etc. in. Let sit for a few days and the rust will wipe right off. Hope this helps.LOL [/QUOTE]
