Default Cometic Headgasket Question

If my engine is overbored with 75.5mm pistons, should i get a 76mm head gasket or will a 75.5mm gasket work?

I heard Cometic recommends that for a stock 75mm bore that you use a 75.5mm gasket to avoid clearance issues. What size gasket should I order? My car is going in the machine shop next paycheck in two weeks!

You can use an oem 81mm headgasket on an 81.5mm bore but Im not sure if thats true with a cometic gasket too. I have an oem 81mm headgasket on my 81.25mm bore. Btw this should probably be in the engine/internal section.
