I though the SRs where the base head. I though all the 440-1 heads flow better. Isn't a ez just a 440-1 with standard exhaust ports?

if you get the big EZ heads that take the offset rockers they would be more like the -1s with the stock exhaust port. but i think the price goes way up like the -1 heads.

i have read here some guys have very stout SR heads. obviously if the head is a standard port head then it will not have enough volume for a bigger motor.
