Duane you are correct. It was originally going to have w2 heads but that plan changed when it took months to get custom valves.
I’ve also since changed to a 4.30 gear ratio. Now I need to work with what I have. New cam is 255/262 .640/.612 108lsa install at 104.
Car did mph same with 3.55 as it did 4.30. But I’ve only made 5-6 passes.
