I just bought some Speed Pro pistons. They are .030 over and forged. I got them from Summit. In the box there was a little white paper that says something about the proper cylinder bore taper or something like that. It has to do with the Durashield coating they put on their pistons, at least i think. Does anybody know what needs to be done to the cylinders for the proper taper or just what theyre talking about? I really need to know so i can put my motor together. Thanks
