Not sure of your question? Are you asking what a GT-40 intake would be worth?......Tubular $300-500, Explorer $100-250, Cobra $200-400

get the heads done up before you put em on

+1 on re-furbishing the heads.

At a minimum put new guides and good springs in it.

If your pulling heads of a junkyard car, no telling WHY it's in the junkyard.

I would swing them by the local machine shop to check them out

or just be a hard ass and slap them on and raise hell.

which gt40 heads are the ones that will match up with a stock exhaust and are a direct bolt on

At minimum they will need to be resurfaced, new valve seals, new valve springs and a valve job.

Non P heads. The Explorer GT40 heads have 65cc chambers which is about 4ccs more than the other stock 5 liter heads. Just something to keep in mind. They can be milled to get the compression back up though.

stfudvs · June 2nd, 2009, 06:39 PM

so the gt40 cobra cylinder heads dont really net much gains unless milled ?

The Explorer GT40 heads need to be milled to keep the compression at 9:1. The Cobra GT40 heads have the same size chambers as the E7 heads so there is no issue there. There is about a 20hp gain with GT40 heads.

1 bag o dicks

stfudvs · June 2nd, 2009, 07:42 PM

i think i will hold off on the cam/intake and just try to get some twisted wedge heads because i dont want to regret settling for gt40's

what all will i need for install
other than fel-pro gaskets and the bolts

93hatch · June 2nd, 2009, 07:59 PM

thats it, bolts, gaskets (valve cover, timing cover, head, intake,) oil, coolant

stfudvs · June 2nd, 2009, 08:45 PM

should i get new spark plugs

93hatch · June 2nd, 2009, 08:53 PM
