.020" overbore and head gasket question
I'm currently having my block bored .020" (or .5mm) over so it's 85.5mm total. I'm trying to figure out if I would need to machine the OEM head gasket to make it fit or will it fit just fine? If I shouldn't machine, then who makes a gasket that's .020" overbore?

im pretty sure the stock head gasket is good up to a .040" overbore on the 4g63.
