Well it turns out in the tear down of my motor that I have a cracked passenger side head.  My heads that I have are ECZ-C's and my friend Alex has a good set of ECZ-B's. Other than the compression ratio, is their much difference in these heads? I can increase compression via shaved heads and/or domed pistons, just wonder if I should use these? 

I would LOVE some ECZ-G heads or 113's but trying to find them locally could be tough. Oh and before anyone says anything, unfortunately, aluminum heads are definitely NOT  in the budget!
