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

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

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

CARTOON. I must admit there was a LOT of acid used in the 60’s and 70’s. …. Especially at Woodstock. Regards.

I can neither confirm or deny 🤪

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.

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