Just wondering becuase I'm going to try some DIY port & polish job on a ZC head I got on Ebay. I got the Ebay head to practice on and I will be buying a ZC motor soon.

area down smooth and did the opening to match the Maxbore TB @
60mm in addition to a bit of work in the runner area
(should have taken more pics though).
