gt40 headers
So I am looking to build my 302 in my truck, and i am looking at gt40 and gt40p heads. I will make that decision based on deals i find and such; but my question is will any 5.0 truck headers fit on these heads? or will i have to get a special set? sorry if this is a dumb question but im trying to get all this done in as few shots as possible.
Thanks
Danny

Stock the GT40P head flow a bit better and makes a bit more power all other things being equal. A little work with a grainder and you can port a GT40 head to equal or better the GT40P.
The "P" head is more numerous as the GT40 head was only sold on 1993-1995 Cobra Mustangs, the Ford Lighting pickups, and the early 302 V8 Explorers through mid-year 1996. That is when they introduced the GT40P. From what I've seen a pair of GT40's can be purchased for around $300. Condition will dictate price but I would not pay over $400 for a pair that is ready to bolt on. The GT40Ps are priced similar and sometimes cheaper as they require special headers and/or different plug wires for performance use.
I paid $300 for a low mile pair of GT40s last year.

I know for a fact that the summit pacesetter shorties will clear the P heads with a small dimple on the number 7 or 8 primary. And that the ford racing SS shorties will require a large dent and a header shorty plug to clear on number 4.
