But the port work costs extra money. That is why I am hoping members will chime in and help out the ones of us that need to save that extra $400 to $500 dollars that this kind of work costs, just for minimals. It can go way up from there, the more work that gets done. The valve job and parts installation is a given to get done at the machine shop. Just looking for some basics. I know my local machine shops won't do any port work. Then I would be getting into shipping costs to and from wherever.
