okay so to make sure i have this 100 percent correct
97-01 explorer's have gt40p heads
96 explorer has the upper and lower gt40 intake with the internal EGR provision which is necessary if i want to remain smog compliant.
Is that correct?
I'll assume you're talking about the heads since you pluralized GT40? GT40's with functioning thermactor system came off a legit '93-'95 Cobra. They were the only ones that were drilled for the thermactor system like the stock E7TE's. The later Explorer heads were never drilled for it. That's one sure fire way of telling if they'r real "Cobra" heads or not.
next time i pull the intake ill double check. i believe when i searched it before they were GT40 marine heads but i dont think my chambers were the right size before rick milled them.
