You can bore a 660 cylinder. Wiseco is a good piston in the 11:1 CR. The next strp for you would probably be a 101mm. Then that leaves room for a 102mm later on. Don't know the best place to buy them. Ebay or one of the site Sponsors could get one I'm sure.

Thats the one you want there. A cometic gasket kit is also a good kit for the 660. If you get the full gasket kit for like 63 it will have your clutch cove a side cover gaskets to. Always nice to have on hand and not much more for the full kit.
