ok i'll say it...ditch the rhineharts while your at it!
Your two piston choices probably being between the cast and forged hi-comp pistons? Realistic compression is a little lower than what they rate them, but using a cometic head gasket would put you closer to 10.5:1, that being with the forged pistons(assuming that's your goal)
also check out bigboyzheads.com for his compression calculator..best piece of info i found when i did my build, besides Dean himself.
