Hi, I got my heads back yesterday, they checked the valves were ok. The heads were not cracked, but they had to grind out and weld around two of the water gallerys due to corrosion, before a .010thou reface. All the valves have been reground and the seats recut, the exhaust guides I was told were in very good condition. The inlet guides were reamed out and k-lite guide liners fitted for very reasonable 220 pounds.
