Dyno testing a stock(?) 1972 440

GREAT thread, and thanks for sharing! Couple of questions. You never mentioned the head gasket thickness and whether or not the 516's were big or small ex. valve. Also, the test was done with a .509..was it installed straight up, or advanced. Also, what of low comp. specific grinds, like the Hughes Whiplash. What's your opinion on these..what do you think the differences would be on the dyno sheet?
