P2R CNC machined heads. They have everything done to them on the market besides cams. Those I kept stock because I’m still running Hondata. I have another J32A2 set of heads that were Ported and Polished by arguably the best Hand PnP’r in the United States. If you have seen better on this scale and difficulty of working are, please share. They also have everything done to them and will be Benchflowed next week to see which set of heads flows more CFMs. A real Man Vs. Machine challange.
