Got Hi Comp Pistons?

Got some L2355 .060 over 440 Pistons. Considering switching to hi-comp pistons as it appears the best I can do is about 10-1. Since this is a race only motor would you go with L2295's instead? Looks like it would take the motor from 10-1 to 12-1. Looking for 500-550hp. Have mildly ported 906's. Considering some aftermarket heads.
