So the guy before me had the heads ported. looking at the gaskets I can tell that the gaskets could be cut away allitle . I am however going to get copper gaskets or at least was thinging about it. How hard would it be to cut away at copper gaskets I know that the edges looked to be raised so I don't even know if you can open them up at al?. Also I was going to get the copper gaskets because the stock ones don't seem to hold up very long. Copper the way to go? anddto you think it is worth cutting the ports on them open allitle?
