what is the stock 5.3 04 comp ratio? [/b]
I believe all the 5.3's are 9.5 to 1. 10.9 to 1 o2Denali? Can you say HAULIN ASS!? With ...yikes.

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.
