to add to that, I am also running the 1.88/1.60 combo valves in my 302s. The heads were mildly ported and gasket matched. I don't have any flow numbers, but most of the research I did pointed toward the 1.88 valves
Garth, it seems like we're on similar paths any idea on gains you've experienced? Would you be able to give me a rough figure on what the head work to that extent might run?
Also, would 360 heads be a better choice due to the fact the valve sizes are already 1.88/1.60?
