So tell me do you know what the difference is between a D0OE, D7OE or a D8OE head castings? one is from 1969 .
D0OE is a head engineered and used in 1970. D=7 0=0 I know how to read casting numbers. Apparently I know the difference more than you do :rolleyes: You are blowing up about something you think I know nothing about again. I know my way around a windsor. You saying they flow better doenst mean anything until it is proven on a flow bench. If it cant be proven, it cant be claimed unless you have a dyno sheet of comparison of that head vs GT40P of the same motor.
