I'm looking for information on Ford experimental heads for the 427 TP. I've been trying to find a set of headers to fit my 68 mustang with a 427 Tunnel Port. I assumed the aluminum heads were manufactured by Dove like the block. I called Dove trying to figure out what I have and they said they have never made a head with the exhaust port configuration that my heads have. When I talked to FPA about making headers for it they told me that Ford had a program with Holman-Moody where they would cast aluminum heads with different exhaust ports and have H-M try them out. They said that all these heads had a casting number between the center two spark plug holes that started with SKS. My heads have this casting number. No one has a listing for heads measuring what mine do between the head mounting surface and the center line of the top exhaust bolt hole. When I bought this engine in my first ERA Cobra the guy who sold it to me told me that it had some one-off GT40 parts on it but I just figured he was trying to justify the high price he was putting on the engine. If anyone has any info on these heads I would appreciate hearing from you.
Thanks.
