maybe, have to try to adjust the cam 1st. But oneof the comfirm reason high high CR. I'm using Blacktop piston with o.5mm metal head gasket. Compression ratio is too high I think. After retard ignition timing, manage to eliminate pigging across 1.5KRPM to 3.5K RPM.your knocking problem could it be caused by the advanced cam? :hmmmm: correct me if i am wrong..hehe. just wondering
