I did some quick calculations.
Estimated you will have the piston down in hole .03
.041 head gasket
flat tops
4.12 stroke

Approximately 12 to 1 compression.

My pistons with a -18 CC dish and same numbers above give 9.79 to 1.

The engine will definitely like a larger cam to help bleed off cylinder pressure at low rpm.
