Just a quick update. I've got the Mahle head gaskets. Looks legit. It's going to seal up the engine side of those headbolt holes for sure. Rest of the holes look the same place. Thickness looks the same. The bore size is smaller (but with just as large valve cutouts). My caliper makes the bore size still roughly 4.250" which is still more than I need so I think this should be something that can only help.
