Upgrading stock 1971 318 heads

Slantsix64, I will say this once on these three subjects and I will not argue with anyone.

1. I have cut heads .040 and .045 and NEVER required a different push rod OR milling of the intake. Never an issue either.
2. Flow trumps compression any day of the week and twice on Sundays.
3. Closed chamber heads do NOT perform as well as open chamber heads, all else being equal.

Hey you can just call me Moe, I have made a cut on a stock 360 heads .40 and the intake bolts on correctly as you stated on another thread . I was just wondering that because these heads are resurfaced would it throw off the measurements of the cut. And being that 302 heads gave the 88 318 motors a bump to 9 to 1 compression does that mean the head milling wouldn't need to be so much? Sorry if I don't make sense
