The heads for my Firebird are made of unobtanium. Lol 3K for a set of castings if you can even find them. I tried getting aluminum heads and the NHRA told me no. “Change your combo or quit is basically what I was told. I don’t really feel that bad for the Chev racers. I’d take 10hp extra to be able to change to aluminum replacements. They just don’t care about Pontiac’s or the people racing them.
Forgot the other combos that got replacement heads that were bigger, runner volume, valve size, etc. to replace heads you can get anywhere or anytime. The injustice of the NHRA. Lol
