ive talked to other people in other forums and they said in 97 they went to p's and the 96 had the cobra and lighting regular gt 40 heads

 

not all exploder heads are the gt40p's
some are regular gt40's.

 

deck man do some searching. 96 and early 97 5.0s in explorers came with the exact same heads as a 93-95 cobra. the 97 1/4 5.0s have the gtps which will raise a stock 5.0 up to 9.6 cr. i have 98 heads

stock headers ill work but its how the plugs line up. some tubes maybe in the way of the plugs so maybe need a different plug boot.

now for his question. youll gain some performance cause of the size of the valves being 184/160 i think but the gtps are 184/same as stock e7s for exhaust. but dont think youll see that much of a gain if you leave them stock. now ported yes youll see a gain

 

all this talk about GT40 heads. will they bolt on any 5.0? I have an 1985 5.0GT bored .30 roller racing cam 10.5:1 comp. flat top pistons, but havnt touched the heads.What do you think???

 

yes they will

 

I just swapped in a 96 explorer engine. The heads say gt on the upper right side and have three notches on the back. These are not gt40p? and regular gt40? i dont understand i was told they were gtp. which one is better?

 

I just got a great idea. Maybe i can go to a junk yard and find some GT40 heads off of an old explorer. Do you this will be easy to do and which type of GT40 heads should i look for?

 

interesting site but nothing about heads

 

It's hilarious to go back after all these years and read some of the MISINFORMING BS that some folks would post, LMAO!!!!
