Explorer head identification

[Stock 77]

This engine is in a 98 model truck so I expected it to have "P" style heads, but upon inspection the engine looks like it has GT heads and not the "P" style. I always look at the angle of the plugs when I can't see any markings. Do these look like GT heads to you here that are much more knowledgeable than me?

Yea I may have to tear into it to know for sure, but I used a set a few years ago and I sure was thinking the plugs came out at like 45 degrees.... these look like their sticking strait out, but I may be an illusion with all the junk in the way

They look like P heads to me.

Those are "P" heads. You can tell because it has an external EGR valve.
