The head gaskets fit the block perfectly. When I checked the gaskets against the heads one head lines up (not well but good enough to seal). The head that is pictured is way off though. If I modify the head gasket dowel location to correct the alignment I will have to move all the bolt holes on the gasket. I sent my head and gaskets to AFR so far all they are saying is that their is nothing wrong with the heads and nothing wrong with the head gaskets.
