Does anyone have a recommendation for a place to take my V-12 heads to have them checked due to overheating? I am in Michigan and would prefer to drop them off. I am good for 100 to 150 miles radius. Thanks! Referring to my earlier post: The former owner overheated the engine, dropped an intake valve seat, and no damage was sustained by the engine. Being the fellow that I am, I am going to be complete and have the heads checked to be sure no other problems are done or lurking just waiting to lay my cat low.
