Indy Heads for the new Duster motor. Poor

They did not build the motor HTA did it before my son worked there. The Heads were put on out of the box minus different springs and retainers.

Now that my son took them apart . He re-did the work that should have been done the first time. We had no problem with the motor It had some track time and a total of 600 miles including street. It ran 10.68@ 128 the last time out at Numidia raceway spinning the old feathered tires

We raised the compression from 12-1 to 13-1 and are improving the heads. should be a lot faster with a taller gear set and a lot less weight . We'll see?
