you mean .010 over right?

You don't want the gasket hanging into the cylinder IMO, the metal will heat up a lot and could cause detonation. But I'm not the bored out Gawd, so I'm not certain

i dont think gaskets are exact 75mm for this reason.. aren't they all a little larger?

usually they are just a touch over.. Well they are for b-series anyways. put the gasket on the deck of the block and just run your fingers down the edge of the cylinder wall and see how bad it is.
