There isn't any water in oil or oil in coolant, but when I start it with full radiator it blows out quite a bit of coolant. I pulled a sparkplug and it was orange looking. I pulled the head and am not sure how to tell if gasket is bad, didn't see any bad spots on it. Could a machine shop tell me if the head is bad?
Yes, any decent machine shop can tell you if the head is good. Look around the fire rings on the gasket for any chunks missing or difference in uniformity that would indicate compression getting into a water galley.
head machined and new head gasket. Anyone know what the spark plug gap should be?
