Did not know about the cam lift spec. That kind of explains everything, my combustion chamber head depth of 0.30 plus the 0.040 of the head gasket is the cam lift! Was more difficult to measure the valve rise accurately as had to keep rotating engine to try to get maximum valve rise. Will think about the idea of grinding the head with a small grinder, nothing to loose at this point. Probably should grind all cylinders as the other exhaust valves have to be right at the edge as well. Can measure grinding progress with straight edge across top of head and a micrometer. Head appears to be thick enough around spark plug area to take a .015" removal?
