The heads were stock C6AE-Rs (Big "R" heads cast at DIF), except for removed thermactor bumps, CJ valves, and mild port cleanup. The Fairlane lip was retained at the exhaust roof as they transitioned into FPA Tri-Y headers.
There are no C6AE-H heads for the FE, so I suspect you refer to the common C8AE-H casting of 1968-71. Similarly, there were no C7AE-F castings, so I suspect you refer to the C7AE-A casting of mid and late 1967. In both cases the heads differ from the dyno'd head. I would be interested in the run using the C8AE-H castings, as this head design was so common from 1968 through 1976.
