This pair of GT40 heads is off of a 1993 Mustang Cobra. These are NOT the GT40P heads that come on the Explorer, these are TRUE COBRA heads. I took them off my car to replace them with a pair of aluminum heads that I got a good deal on. These were on my 94 Mustang GT. I am only the second owner of the heads, I purchased them right from the original 1993 Cobra. These heads are in perfect working order and are ready to bolt right onto your car with no prep work required. When I bought them, I had them hot tanked, had new valves installed, new performance double springs made by Crane I beleive, Neoprene seals, Isky adjustable guide plates, 7/16 studs, and 1.6 Proform Roller Rockers. The air ports have screw-in plugs for no smog set-up. The heads only have 3,500 miles since rebuilt. I used these heads on my 306 with a F303 .512/.512 cam with NO piston to valve clearance issues whatsoever.
