The more likely culprit is that the head was milled which made it too thin. If the valves are indeed hitting no matter how lightly, you made need to find a copper gasket which is usually thicker or can be ordered that way. Not sure but I believe Olson's Gaskets in Washington State has or can make solid gaskets in special oversize thicknesses and may even have some in stock.
