very nice, but is all that polishing worth it or even beneficial? I was always under the impression the finish left from a good bit of machining or grinding will create a faceted surface ideal for gas flow, the golf ball effect and all that.
very pretty though!

murnan's are the fastest by far. thats if your lookiind for H.P.

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.

Hope this will help.
