I have a 1972 302 in my 67 mustang. It has Trickflow Street Twisted Wedge heads. I run a Weiand tunnel ram. I am having a problem finding the correct gasket unless I am missing something. The front coolant chamber opening on the gasket is off by 1/4" so it will create a restriction on one side and leave the head exposed on the other. The other problem is there is a corner on the gasket pertruding into the coolant chamber opening with a hole in it that covers about 25% of the coolant chamber. Other than that the gasket is perfect. Summit and Trickflow both say that the felpro FPP-1250, the one described above, is correct. Any thoughts would be appreciated!
