Well, I have been starring at this thing now for a few days very closely. The Felpro will seal around all the water ports. I have looked at it up to sideways unless I am missing something and Hughes, Don at FBO and Indy don't know what the heck they are talking about??
Hughes and Indy have running engines with these gaskets 519SD Perma Torque, that is what they say anyway...........take that for what it is worth...
