As long as there is no positive deck height, and a stockish cam, would a set of thinner gaskets help get a little bump in compression, like a set of .027 metal gaskets? I recall that the 440's came stock with those.
not sure its worth the trouble.. when my block was at the machine shop they indicated that a full compression point would only gain maybe 40 hp. don't think you'll get a full point from thinner gaskets. this is what i'm using on my 360, .028 compressed..
