very pretty though!
Polishing doesn't worth a thing, just waist of time!!!
With Brian Kinney from Xdyno we did some test and max RPM and HP we got from motor which was plain from cutting tools, no polishing no massaging and it was 45 K with .92 HP on his certifyed dyno ( just for comparicing RB 5 ports Rody modded 43K and .9 HP). No cuts on sleeve, no turbo scoop, but big chamfer on exit of center hole, basecaly its look like stock engine but with my P/L set and my cranck.
