I am going to try using the Milodon copper head gasket. If you want to check them out, go here and click GASKETS and then head gasket.

They are made for high compression applications. They suggest that if they are driven on the street that you use silicone around the water passages. Milodon actualy has more sizes that you see here...so you can alter your compression setting as well. I believe they have .030 .040 .050 .060. These are 4.06 bore as opposed to 4.10 bore and so you might do a compression calculation to be safe as well.
hope this helps
