Use a .020 Superformance steel shim gasket coated with gold permatex spray. I think they are ~ $25 a set.




<tap> <tap> is this thing on? Call Greg and he will hook you up.


I was told by 440 Source that it has to be a multi-layer gasket, and not to use a steel shim gasket

Production Mopars used steel shim head gaskets, about .020 thick. FelPro composite head gasket is app. .040 thick. If you use the thick gaskets and cut your heads .030, you've only affected the factory geometry .010 - not enough to require milling the intake manifold or the intake surface of the head. So just cut the deck surface of the heads .030, which will give you the extra half point compression you're looking for and you're done.
