what are the exact markings to look for on gt40 heads and intake set ups? i called and asked about 97 explorer heads/intake and he says they have em but i wanna make sure i get what i want. anyhelp will be apprecaited thanks

easy way to tell is gt-40's have angled plugs and P's have straight.. on the front of the head there will be a 3 bar marking for gt-40's and 4 bar for p's

Whats the diffrence between the P's and the regular GT40's ??? And which set would fit on my 93 GT ???

Thank's...

regular 40's have 1.84/1.54 valves, not sure what p's have but p's have slightly smaller cumbustion chambers and require unique headers or bbk shorties to work in a fox

you have to have p specific headers to run p heads,they flow better but u need new headers for them,the plug is at a different angle.

yah but there is never anything wrong with getting new headers other than the stock ones =] i have bbk shorties with my gt40p's, ***** thumpr cam and with the stock intake and i could tell a big difference,just got the cobra intake put on but it has to sit while i wait for stupid elbow

i already have BBK shortys, i was thinking about the GT40's for now , until i get the trickflow heads in the future, anything is better than stock! im sure a set of GT40's will hold me for awhile, along with intake etc...

Anybody know what year explorer i would need to get the heads off of ??

rebelcowboy

a 96 if u want gt40s,mid 97 up if u want gt40p's

ilovemy95gt

why not just get the gt40p's now, if u go to a junk yard they are usually same price, and then u wont have to get the p's later, better flow im telling you!! its the best way to go

ok cool, should i run the GT40 intake/ or jump to the Trickflow? and also looking at TF Stage 1 cam..
