I know if it does is the have them is the GT40 because they have the TFS and the GT40P I bought dont.

I had a hard time reading this jibberish... but no, that is a FACTORY 94-95 GT intake manifold

six of one, half dozen of the other. The P heads are "technically" a better head...

If you mean those stock hunks of crap? i guess so... But you would be better off buying some MAC unequal shorties, or FMS unequal shorties

hot tanked (cleaned), pressure checked, and milled as little as possible to achieve straightness
There is also a spring kit available for those heads. I'm not sure what the part number is, but I know its made by TFS. MJR46 might know what the # is. If you get those springs. have the machine shop install them instead of putting the stock springs back on.

LOL sorry for my spelling in that first paragraph,

About the headers the car came with aftermarket headers but the reason I asked was that because of the spark plugs but I'll have to check on that once I have the other heads out.

The header are exactly as the one in this link I doubt they are bbks but the ex-owner say he paid $450 for them so I'll have to check them later on.http://www.brothersperformance.com/p...ceramic_lg.jpg

if the yard has the gt40 (not p) heads just grab those and then you can use your current headers and save urself some money and hassle. they perform about the same

There was one set of the GT40 but the bolts that bolt on to the block had so much rust they strip out just by touching them, so I found the mountaineer with a clean set of GT40P and had no choice.

Anyways what I'll do is put the stock ones for now until I receive the other ones and sell the ones currently on the car they almost new so hopefully in ebay they'll go for a descent price.

Now I want to get a set of roller rockers which ones would be suggested for this heads?
