Use a 61mm gasket for big bore

Post by Geeky160 » Wed Aug 20, 2014 6:04 pm

I'm rebulding the top end of my CL77 with the old big bore pistons and new BB rings 63mm. I haven't found a big bore head gasket yet. My question is, is there anyway I can modify my new 61mm as measured head gasket to work with this setup? Thanks
