Replacing head. What else should I replace?
So I am replacing my entire head with a new one for my 2002 gt. I am replacing the water pump, spark plugs, head gasket, valve cover gasket, serpentine belt, and vacuum hoses attached to the head while I'm at it. Is there anything else relevant to replacing the head that I should change while I'm at it (o2 sensors, chain tensioner,ect)? Does the chain tensioner have a tendency to go out or leak?
