If running on 87 octane gas is important to you then stop there. But if
you are willing to go with premium then you can probably go all the way to
10:1. I had mine shaved to about 9.5:1 and I have no trouble running on
mid-grade. If I had it to do over I would so 10:1.

The Poor Man's way is to drop the pan, pull the #4 main cap and stick a
feeler gauge between the crank and the shim.

Or you might find a machine shop who will do it for $60/hr
