I asked previously for a set of 428 PI heads for a correct 67-GT500 engine build. Are the C8AE-H heads the correct ones? Seems they are, since they were being cast as early as 1967.

The other two issues regarding what is correct OEm equipment on such an engine:

1. What type of air cleaner did the 1967 GT-500 come with? Pls. note, this car came with the PI intake w. one small vacuum Holley carburetor.

2. Exhaust manifolds: What type of exhaust manifolds were on this engine when installed in the Shelby Mustang?

Thanks and happy motoring to all FEs.
