I am wanting to get every little bit of compression i can without being over the limit. I tried an ac plug R45LS6 and it sticks out of the chamber .062 which is to much with only .040 clearence from head to flat top piston. Has anyone tried this and if so what part number?

don't try to get more compression with a plug,the gain would be very small and not worth the problem.i run AC R44
