Building a 402 H/C lq9

How much CR can I go before having to switch to race gase? I'm trying to decide on pistons right now and I'm trying to figure CR?

a good tune can help you out . i know cars running 12 and up .
to give you an idea 11:1:1 is going to be about a 59.96 cc give or take a few . 12:0:1 is going to be a bit over a 54cc chamber . 15:4:1 compression is 38cc which is a c5r head .
