First pic is a Cometic, second is the TF recommended Fel-Pro 1009.
The Fel-Pro is right at the edge of the square. I put some bluing on the head and scribed where the end of the head gasket lays.
I'm thinking there's gonna be a little leak here if you don't do something about it.
I also have a Victor graphite faced gasket here that was wide enough in this area that it would probably seal this off okay, but the gasket fire ring was ever so slightly inside the chambers in a few areas.
IMO, for the next batch of castings, TF should just fill these squares in. There is one at each end of the head, and they both have this same issue.
Got a call from TF and they are listening because I brought up the these holes and they are going correct this problem in the next castings. They told me if I had my heads and hadn't put them on send them back but if I wanted to use them just fill the holes in with right stuff. He said they had done alot of testing and assured me they were good but they wanted to go ahead and fill the holes in. If you guys have any ideas and suggestions to make to TF I suggest you call them because they are trying hard to make us a very good head.


FWIW, the Eddy RPM have a couple casting pockets in the head mounting surface too. Theses actually go edge on edge with the block water passage, and would appear to be a real potential for a water leak, but they don't seem to, and nobody seems to care either.
