Low buck 360 build
A couple hours work with the die grinder and a burr, the bowls were done as they were going to get. I also removed the smog bump in the exhaust ports and a very minor port match, which probably will not make much difference.
These old 360 heads had the strangest exhaust short side radii. Anyway I smoothed it as much as I could without going crazy with anything. Just left with a burr finish, no sanding rolls.
