The previous owner told me he had these on a large cube windsor motor with a .630 lift solid roller cam. The motor dyno'd 703hp. He said these heads had been sent to New Jersey and had a "stage 2" port job. Take all that for what its worth. All I know for sure is that my machinest said who ever ported these heads knew what they were doing, he had never seen a more beautiful port job. He actually called in friends to look at them, so they could see what a good port job looked like. The heads were disassembled and cleaned, then valve seats were reground aswell as valves. He did notice that the exhaust valves were sunk alittle. He said they were still good to run but you may experiance alittle shrouding. Nothing to worry about.
All machine work is done including surfacing. These are ready to bolt on and run.
Valve side is 1.94 / 1.60 and should flow 300cfm/200cfm at .600 lift, and 315/210 at .630
I am asking $750 for them.
