G'day all, You don't say whether you had a head gasket fitted when you determined that the valve was touching the head. If you didn't have a head gasket on you need to measure the interference with and without a head gasket fitted (loose not tensioned). You also need to grease-up the valve tops and determine which one is touching the head. I would not recommend two head gaskets. There are firms around which profile cut all manner of materials with water. If it fouls without a head gasket and does not foul with one you may need only a few thou to clear during operation. I would have a solid copper gasket made to a yet to be determined thickness dimension. It may cost you a few hundred dollars but it should last. My 54 Caribbean head was very eroded and warped but it was welded, milled etc and came up fine. Get a few more opinions before you decide on a plan of action. best regards Peter Toet
