thanks project rs.ive heard of the decomp plate but is there anyone on here who is using one to effect.Its got to be reliable i would rather spend say 500 on pistons then have a load of problems later on.All the other mods wont be a problem i have access to a laith and mill machine.Am also gonna plug oil returns on cylinder block as well as head gasket to be sure that wont fail just unsure what to do about compresion
