Bump, was looking for some ideas on DIY squish cutting for this behemoth of a head for a very special kit/project.....
Very clever rotating the head on the spark plug threads, as you turn the threads you advance the head further into the bit, but I'd think that would make for a spiral/uneven squish no?
Anyway, if you're trying this...I would get a "contour gauge" like this to help match the piston dome's profile to the head!
