what heads to use for a 408 street stroker.
if one HAD to use factory cylinder heads to be used on a 408 street stroker and cylinder head volume
did NOT have a role in determining compression ratio, what would be the best head to use.
1: 4v closed chamber 2.19int 1.71exh
2: early 4v open chamber 2.19 int 1.71 exh
3: late 4v open chamber (2.041 int. 1.65 exh
4: 2v open chamber
what choice do you think would flow the most and why ?
what choice do you think would deliver the most low end torque and why?
remember: cylinder head volume would NOT be considered in making compression ratio.
