I agree, I'd consider actually taking another .015" off the deck. It will bring the compression up to 11:1'ish, but with the tighter quench will give you a better chance at pump gas...

I ran a small block at .030" quench at 12.2:1 on pump. Get the 440 up around .040" quench and 11:1 with that much cam and you'll be ok.

Worse case you have to take a couple of degree's of timing out of it.
