I don't have an answer for you, but I'm moving this to the building and porting section.

On page 2 of this forum there is a thread on milling the housings. You wont need to worry about coolant seal grooves but will need the o-ring grooves around the dowels

I did it, thread below



https://www.nopistons.com/forums/index.php?...mp;#entry879231



FYI: You only need to grind 5mm off each side. - 10mm will get you a low compression engine
