Another option to consider is using a Cometic MLS head gasket -- they are available in a whole range of different thicknesses. I'm using them on my highly modified 42 Merc engine in my 32 Cabriolet (wanted to try them - so far, so good). They are expensive (about $250 a set), but time is money - so maybe a set of .070 ones will help you. They will not compress like other gaskets and many folks reuse them.
