Exhaust Port Size and Shape?

[GearHd6]

I've got a 91 Mustang with a 5.0 engine with stock heads and im trying to order some gaskets before I get the headers off so im all set to do it in one day. But it seems like theres a few different port sizes and shapes. Which ones will I need? Thanks.

I have always had good luck with Felpro 1415's.

So they're the square ports then? I want to try either the copper or aluminum gaskets, just wasnt sure of the shape.

yea square ports. I ordered some one time and i specified Ford 302 and the dumbass sent me Chevy 302 gaskets. I mean...i specified Ford and which engine is by far more plentifull? Make sure you state that you want FORD!
