I believe it is...IIRC, the earlier '96 heads will be non P, the previous owner of my Mounty told me it has non P's on it...but it's an October '96 build so I'm not 100% sure, and to be honest, I've never bothered with looking. I've got a leaky manifold gasket, so I suppose in the next couple of days I'll figure it out. I can probably look in the fender well and see if the plus come straight out (P) or if they have an angle (non P), rather than look for the hard to find 3 or 4 bars cast into the corners.

Not that it really matters which heads my Mounty has as I'm by no means tearing it apart LOL, but since the thought came to my mind....I went to look...no P heads on my Mounty. I did some online checking real fast and it seems that the mid-late '97 built Exploder/Mounty would have the P's. Just say '98 up to be safe, if you're set on the P's. Just go with something like BBK 1515's and they'll work on P's and all other SBF without issue, in a Fox car, that is.

i guess i lucked out, the 96 i got mine from had the egr ports correct to our cars..i think thats "internal egr"

Just a FYI: all GT40/GT40P heads have internal EGR passages. I ran GT40Ps with the stock functioning EGR system no problem. The EGR port is the small square between the front two and rear two intake ports. All factory Ford GT40/GT40P heads have internal EGR passages. The GT40/GT40P heads used on the Explorer/Mountaineer don't have Thermactor passages (the holes on the rear of the head). Those have nothing to do with the EGR system. The Thermactor system injects fresh air into the exhaust, either in the heads or just before the catalytic converters depending on which solenoid is open, to warm up the exhaust to light off the catalytic converters. If you have no cats you don't even need to worry about the Thermactor system. The only problem with GT40Ps is header fitment. You'll need either a set from BBK or FRPP to get a decent fit with the GT40P plug angle. I ran (and am still running with Edelbrock heads) the set from FRPP because it's made of stainless steel.

The confusion on GT40/GT40P EGR passages usually comes from the intake manifolds used. From 96-mid 97 the Explorer's with GT40 heads used an internal EGR style manifold while the later Explorers with GT40P heads used a manifold with no internal EGR passages. This causes people to assume that GT40P heads have no internal EGR passage when in fact they do. Crazy thing is all Explorer/Mountaineer 5.0s use external EGR even though the 96-97 manifolds have internal EGR passages. Go figure. I've included two pictures. I've got a picture of a internal EGR Explorer GT40 intake and the intake where you will note the lack of an internal EGR passage. I also put up a picture of the intake on a GT40P head. Notice how it has the internal EGR port that all factory Ford heads do.

Not that I did a lot of research before I ran GT40P heads or anything. Now this is stuck in my head even though I no longer own a set of GT40Ps :hick:.
