Does anybody know the Iron head casting numbers(last 3 would be fine)? A guy on another forum asked. Something about NHRA rules or something. Figured if I could collect them, I could pass them on to him. I never thought to check the numbers when I was working on my cars, and I won't be in the valvecovers for some time on mine.

:)
