Seriously, I think the best way to go about is to do a set of pistons. The KB 107 units are an excellent choice and you'll just need to add rings and a balance job.
OK, it' expensive by compare to a milling, but that also avoids mis-aligned bolt holes and intake sealing/bolt hole alignment. I hate going down that road of milling to fit. It is a pain in the donkey butt!!!!!
You'll be ahead of the game very well with new pistons. A .039 gasket will hand out a 9.8-1 ratio. A .050 cometic can drop it about another 1/4 point. to near 9.5-1 pump gas super freindly. The limit of a good quench.
