I'm probably over-thinking this, but it seems like the typical y-block bore size doesn't have a Flex Hone that matches well. I'd like to brush hone the walls after running the glaze-breaking cylinder stones in the bores. The 3 3/4" is just a hair too small for my 292 +.040 (3.79"), and will be rather too small for a .060 over 312 block (3.86") that I have.

Best regards,
