Approval of Super Stock Class Aftermarket Cylinder Heads

SBillinson · 04-27-2023, 10:35 AM

The way I see it, for super stock only, if the follow criteria are met, what difference does it make to approve a raw casting?

Correct valve angle
Correct valve placement
Correct port heights
Correct chamber design
Correct CCs

What am I missing?

For those who may think the existing NHRA aluminum heads somehow better represent the factory heads they're replacing, send them to me and give me two days with a tig torch.
