I have a new head with a small scratch near one of the sealing surfaces for a cylinder. I think it is the reason for persistent small pressure leak to the coolant. My leak might also be caused by a not smooth enough surface on the head so....
-Can any one recommend a machine shop in the Montreal area that can take a very small amount of material off the head with the prechamber plugs in place?
-How smooth should the surface be and what did you use to get that way?
