Billy, I'm actually working on some stage 6's at the shop now.

It's one of those things where.......the customer already owns them.......and you can't quite get into a set of comparable new heads for what it would cost to get these into shape.

These happen to be brand new, but I've had a few sets of used ones come through the shop where there was a good argument to be made that it might have been better to cut your losses and move on.

They still trickle into the shop from time to time.

In the case of the Pro Comps....... it wasn't really any fault of the heads themselves that resulted in the dropped valve.
I'm sure if the same parts had been installed in a set of Ede Victors, the outcome would have been the same.
