Got it...
5.3 with .040" milled 706 head = 10.13:1 with a 3.910 bore .054" thick head gasket.
5.3 with .025" milled 706 head = 9.87:1 with a 3.910 bore .054" thick head gasket.
Thinking I might want to go .025" to keep using regular 87 octane fuel.

Maybe split the difference between .025 and .040 and go for like a .030ish mill or something
