I have an exhaust manifold gasket from a 4.2L AJ-33 here.
I had previously checked the measurements against the Windsor 5.0L, Coyote 5.0L, 4.6L Modular and the 3V Ford V8's, no match whatsoever.
The AJ-V8 has oval ports. The Windsor has square ports, the Coyote & the Modular have round ports. The 3V Ford V8 has siamese exhaust ports which are again different.
So i'd be surprised if the AJ133 5.0L would be the same...

We may still not find commonality between engines, but head comparisons need to be at the deck, not intake or exhaust ports.
Just thinkin out loud...

But as far as aftermarket parts such as headers or intakes are concerned, the commonality of the ports is crucial. The catalytic converters look to be strikingly similar on the new mustang 5.0s and the jag 5.0s, judging by online parts diagrams. I've been trying to search and cross check part numbers but no luck yet.
