LS7 Repair Wrap Up: Some guys asked about the relative hardness of the welded on material. In short, it isnt going to be as hard as the heat treated head, but in chambers only creates a variance in finish/aesthetics. However, obsessive being our modus operandi, there IS something that can be done to improve that... Pics below are chamber shape CNC roughed w/ material to spare, and then careful peening to work harden the welded on material. At this point we can just take care of the spark plug via tapping or a thread insert, and CNC contour them like any other head.
