In addition to taking 30 mil off the head, you can also use a .030 head gasket instead of a .050, which will get you 9.5 CR (or so). You can also deck the block, which has benefits in the squish department as well as raising CR. I would do both those things and shave the head last, if I were rebuilding an entire motor. If I were leaving the block alone, I'd at least go for the thinner gasket.

The later, thicker-flanged exhaust manifold flows a lot better than the early separate one, so you can make up the difference by using -- carefully -- flat washers cut nearly in half on the studs common to both intake and exhaust.
