Just looking at what pistons I have,they are KB237 .30 over and my cam is a CRN 689531 hyd roller with 1.6 rockers. What would be the best CC head? And what would my compression ratio end up at? It run on 93 pump gas now and would like to keep it on pump gas but get as much out of the new heads. If I am remember right I am at 10.2 with the 906 heads.
Thanks for all the help!
