Maybe an other head producer in the game.

You mean like Pontiac did with Ram Air V heads? Yeah.

Love me some Pontiwreck Ram heads! I raced a 68 Firebird for years. Had to fabricate my own headers and went with the three pipe design due to the constant battles with sealing on inner two ports being so close. I can’t tell you how many times I heard “ man dude that is the fastest Vsix I have ever seen” They would see the three pipe header and totally miss spark plug wire count or the fact the center tube was much larger than outsides. Morons!
Fun car.
