OK I'm confused on MOPAR Tunnel Ram P4532175

The casting numbers are not the “part number”.
The part number is what’s in the catalog…….and on the box.

W2’s have different bolt spacing than std heads.
Just lay a std gasket against the manifold and see if the bolt holes line up.

My old MP catalog does say the w2 TR has oval ports, but the W5 TR has rectangle ports.
