I didnt get much done really, just hardness and pressure tested bronze guides bigger ex valves seats recut just a smidgeon of edges rounded off. It cost me $150 but that was mates rates. Its nothing really flash but I just condemnd 5 or 6 heads that were rooted and its very rare for me to spend big monet . I usually sneak by doing everything on the cheap. So its nice to know I wont have to touch it for ages.
