Mine were done at More Performance in Charlotte, NC. Ready for this Hit Man X... 2.02 and 1.6 are my valves. Shaved .010 off head. Really just a "clean up" shave. They call them Stage 3 heads. There were fairly expensive, however I bought them out in a package with JE custom pistons and other items so I curved some costs by one stop shopping. Walked away paying $1450 for just the heads.
