Like I said I havent finnished this yet, and all the port work you see I did myself from a stock cylinder. There are several hours of porting time into it so far. I dont polish anything in the intake just sand blast to bring out any tooling marks. Then smooth everything out and sand blast one more time. The exhaust gets coated instead of any polishing. It works much better and carbon doesnt build up on it plus it dissapates heat better. Once this is back from the welder and it gets bored I will finnish the port work. After that its off to the plating company for nikisil.The port work dont look too bad but they didnt do the polish on it to really smooth it down. Some places dont do polish work anymore because some argue that you get better #'s with disturbed air flow vs. smooth air flow.
