Tom, no ridge at all in any of the bores, after talking to a few stovebolters and doing some careful measuring, I will more than likely ball hone it and re ring it with the stock pistons. Probably will be resting in the mounts in my 53 this summer. Wally this came out of a 62 C60 and it has been in bypass mode the entire time, maybe it was a rpo to have it either way? Others might know.
