          I'm pretty sure that Traco used Valley Head Service to do full race porting for Penske's Trans-Am engines that Traco built. Valley likely did other Penske engine head work for Traco including big blocks for Can-Am and even the five-liter V-12 fom his Ferrari 512M.

          It's nice to know they are still around, and I expect they still know what they are doing. If anyone wants their OE heads massaged (pocket porting, port matching and chamber relieving, not full race porting) I'm sure Valley can do the job right.
