before i go and put my engine back 2gether for the god knows how many time if u run over size pistons do u need a different gasket? also how do u guys check the rings? as i have a spares of pistons i mite try but it means wasting a head gasket?

I believe the head gasket needs opening out to match the increased bore.. but i could be wrong, ive not actually built a big-bore zxr yet.
