As long as theyre not "P" heads, they should fit. Any idea what kind they are? x, etc?

they just say gt on the front corner and have 3 bars at the front and back and i was the told the p's got 4 bars and say gtp also do i have to convert to mass air to run these heads and i got the gt40 explorer intake to

the heads you have should be the straight gt40 heads. The gt40p's do have four bars. Gt40 heads should not cause a problem when it comes to headers, from everything I have read.

Look next to #1 spark plug hole, a GT40P head has a "P" cast right into it. Headers will work just fine if they're straight GT40 heads.

they say just gt no p also im gonna throw my 88 cam in my 96 engine do i have to use my lifters from the 88 or 96?

Re: will my headers fit my 5.0 with gt40 heads
 

Use the lifters from the '88 and DO NOT MIX THEM UP. They have to go on the same lobe they came out of. Lube the heck out of them too, good assembly lube. Then pray to the cam gods that it doesn't wipe the cam out.

Let me get this striaght you have to change the cam and you are putting a "stock" mustang cam in there.

You have decent heads, do yourself a favor and install a decent cam. :rolleyes:

Re: will my headers fit my 5.0 with gt40 heads
 

well, I am not sure a new cam is all that neccessary. I have ported my e7's extensively, gasket matched...and all the good stuff. They should be good decent flowing heads. I have been under the impression the stock cam will respond well to the opened up heads. Do not know yet, since the weather is not good enough here to test them out.

You guys think it is needed for his set up to upgrade cams?

If you use the stock cam your going to get inferior horsepower. Upgrade them. Its for the best.

Re: will my headers fit my 5.0 with gt40 heads
 

upgrade what?

Re: will my headers fit my 5.0 with gt40 heads
 

he was saying upgrade the cam.

i got no more money for this car the only reason i got the heads and intake is because i lucked out and got a whole 96 explorer motor for 150$
