Any views on best head gasket to use when running 91mm pistons / Darton sleeves? Thanks in advance Stu

We carry sce Copper head gaskets which are availiable in a variety of oversizes. The only problem is my sce catalog is misprinted.
I believe they come in 88 90 and 92mm size. What thickness of a gasket were you looking for? I will try figure out the right part number for you.

A little less than std thickness as we are looking at 13:1 cr - IIRC the pistons normally give 12.5:1 and we won't want to take much off the head face! Thanks Stu
