Explorer engine swap

[Stone0928]

I was wondering if my stock exhaust manifold would work on a explorer engine with gt40 p heads.

Yes.

They didn’t work btw

P heads have a unique spark plug angle that makes it difficult to use with most headers. Guys have managed to make stock style headers work with a combination of 45 or 90 degree spark plug boots, and thermal sleeves on the wires.

Ford racing used to make a P-specific header that has been discontinued. You might be able to find a used set. There arer also some aftermarket headers that do work.

I ran into that with World Products Windsor Jr heads. I ended up cutting the flanges until they worked.
