GT40P Heads

[Cobraguy]

Can anyone tell me when the newer GT40P heads first appeared on the Explorers? I have a guy trying to sell me a set of heads off a '96 he says are factory equipped GT40P heads..not just GT40 heads. I thought it was like '98 they first appeared. Or am I totally confused? Any help would be appreciated.

The first showed up about half way though the 97 model year, anything 98 and up will have them for sure. You can tell if they were the p heads because they will have the external egr on the exhaust manifold.

Ask for a picture of the casting number
there is a "GT-40-P" cast right into the p heads-

Or the 4 little casting "bars" on the edge of the casting. visible when they are installed- here is a pic of the bars:
