Re: 302 aluminum heads
Please be careful here. Like Jim mentioned a lot of the aftermarket heads listed as "legal" by NHRA for Super Stock ship with valves larger than stock. I have a set of AFR 1399 heads on a shelf. They are listed as legal in the Classification Guide but ship with larger than stock intake valves. The work required to fix that is costly and destroys the advantage of head. They shouldn't be listed as legal. They aren't.
