Product Description

GT40P Cylinder Heads 59cc
Give your 1979-95 Mustang additional power at a great price with a pair of GT40P cylinder heads! You no longer have to go searching for an Explorer in the salvage yard. In the past you would have to risk using a set of used heads that may or may not have worked. These cast iron cylinder heads are completely re-manufactured and ready to go. This set of GT40P cylinder heads features a 59cc combustion chamber to allow higher combustion rates than many other heads including the regular GT40 heads. These heads retain the use of the stock pedestal mount rockers which makes your factory valve-train a direct swap.

Spark Plugs
The Motorcraft AWSF-32C spark plugs must be used to allow these heads to function properly.

Headers
The use of GT40P specific headers is required (M9430P50 and M9430P51). These cylinder heads have an augmented spark plug location that places the spark plug at a different angle.

Specifications
- Intake Port: 145cc
- Combustion Chamber: 59cc
- Intake Valve: 1.85
- Exhaust Valve: 1.46
- Intake Runner Volume: 145cc
- Oiling Style: Through Pushrod
- Brand: Re-manufactured Ford OEM
- Material: Cast Iron
- Factory Valve Springs

Re-manufacturing Process
These heads are original Ford GT40P cylinder heads that you would find on Explorers and Mountaineers. They are re-manufactured in the USA and are NOT foreign made. These re-manufactured GT40P heads start as good Ford cores that are disassembled, cleaned and visually inspected for any defects. Then the heads are magna fluxed, inspected for cracks, and then cleaned up to ensure you receive a ready to bolt on set of GT40p heads for your Fox Body or SN95 Mustang. Rocker arms are sold separately or factory ones can be reused.

Installation Disclaimer
We recommend following the OE manufactures installation procedures and closely following all recommended torque specs during installation. Failure to do so can cause premature component failure.

Application
- Fits 1979-1995 Ford Mustang 5.0/5.8

Note
- Valve springs included with cylinder heads are factory valve springs compatible with factory 5.0L H.O. camshaft. Aftermarket camshafts will require TFS-2500100 or similar.

    I have a pair on my 1983 mustang. Very nice head and it does increase the horse power and the torque. I have a different style header they recommend and I use a 90 degree spark plug boots.

    Yes, I would recommend this item to a friend!

    I love them because of the raw power you can get from them. But i bought without thinking about it and they didn't have a spot for the thermactor on my 92 GT. If you're not worried about Emissions in your area they're great, but if you need to be emissioned your going to be in a quite a pickle

    Yes, I would recommend this item to a friend!

    5 Stars   Ford fit and great value
    By on 4/11/2016
    These heads are inexpensive but I like the fact they are Ford production heads. Also a little higher compression is nice. The proof is in the dyno!

    Yes, I would recommend this item to a friend!
