512 pump gas build question.

I'm building a 512 pump gas friendly motor for the dart. Trick flow aluminum heads 78cc , single plane intake etc, etc. Cam looks to spec out at .620 intake and .627 exhaust lift with 1.6 rockers. 292 297 advertise duration 254 260 @.050.

The cam specs call for a motor at 10.5:1 comp ratio. With the parts listed what would be the max static compression ratio I could go and still run 93 pump gas? I'm looking at around 11:1 with the current available pistons on the market
