Please forgive the dust/carbon/cobwebs.
I'm selling a set of PRC stage I CNC'd heads that I bought off of a member of this forum. I've owned the heads since early September and they have been sitting in my closet since then. They are complete heads, with stock rockers and valves and TSP dual beehive springs good to .660 lift. They are unmilled so they have a 64cc combustion chamber.I'm selling because I'm in pharmacy school and to be honest I need the money for basic living expenses. You can see on some of the pictures that the CNC porting rings do not go all the way around the intake runners. I was concerned about this at first, but asked around and was told this was fairly normal. Basically the CNC porting only takes out a predetermined amount which allows consistently reproducible flow numbers and in some cases taking out more than the predetermined amount would be detrimental to the flow numbers. I've tried to upload pictures that show the quality of the porting, but it's kinda hard since I don't have a shop to clean the heads up so please forgive the carbon and spiderwebs. Any questions, please PM me.
