my 90 engine is getting a new head . It just so happens that my 95 head measures up exact and is already rebuilt so it will fit what I noticed was the 90 head gasket only had really small holes in the water ports but the block and head have large triangle ports would it help to drill out the gasket so more water flows through the whole head instead of just the ends... does the 95 head gasket have better water ports or is it the same 1/4 inch holes as the 90?
