Ok, I've been battling this overheating problem forever, and it has to be internal, because I've tried EVERYTHING else (please don't ask me if I have a fan shroud)!!!

Now, I'm tearing down the motor and I bought some new head gaskets and I noticed something interesting. The water ports above/between the cylinders don't match up. The Felpro 8519PT-1 only has a "slit" in it, but there is a nice sized hole in the head and block obviously restricting the water flow. See pics.

Do I have the wrong gasket?

What do you recommend?

Desperate and I want to get this done this weekend. NO theories, just answers please!!!

Thanks in advance!
