Hey Gang,
I need help identifying who makes these heads. I have heard they are Ford GT40 heads but they should have a fORD LOGO OR PART NUMBER THAT IS MISSING. tHES HEADS ARE ALUMINUM AND HAVE ADJUSTABLE 3/8" STUD ROCKERS WITH GUIde plates (sorry for the cap lock). There is not a part number or logo or anything I can find on the heads I can find. They do have 11/32' valves and that is about all I know for sure.

Anybody have an idea who makes these heads? I would like to know more about the CC volume and runner size etc. but need to identify who makes them first. I would appreciate your help here. THANKS Jeff C
