I don't think that's too high, Dean.  I would say with Cometic head gaskets you could go to 15:1 - Jay

my initial target numbers were a full point lower but measurement after assembly shows I am higher than I feel comfortable with. I know what detonation can do !

I have a cast Iron Pond block with Cometic head gaskets with 14+ compression ratio with no issues.
