Indy Heads for the new Duster motor. Poor
My son took the Indy heads apart from my new motor to check them. Indy never cut the 15 above the 45 degree on three of the intake seats. The 45 degree was 1/8 inch wide . The lap went to the end of the valve.
Also two of the exhaust were 50 degree's under the 45 so we re-cut them all to 65 degree's. They also never blended the bowl to the guide on three exhaust ports. For what they charge for 360-1's you think the quality would be better on the machine work. He ended up re-cutting all the valves and seats. The guides were also a little loose but he said they would be good for a season or two.
I am not happy with what he showed me. Anyone with these heads should have them checked
