My compression ratio is way too low after switching to my new AFR heads, I got a good deal on 72cc's so I went ahead and got them. How much can I take off from resurfacing to pick up some compression without weakening the deck without making the head too weak for boost? I like to pick up one point in comp.
Is that possible? Whats the smallest chamber size I can go before I start having trouble?

It's not about making the deck weak it's milling them to the point where the intake manifold will not fit on the heads anymore. I wouldn't go more than .040", you can go a tad more than that but then you have to cut the intake manifold flange to get the manifold to seat as well.
