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 ,

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.

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 ?

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 !!

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

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!

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

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