I don't think the gaskets are the problem as much as the bolts but I had no indication that the oil was
wicking up the threads until I took the intake off. The clown I bought it off of, from Joe Namath's hometown, certainly knew because he changed the plugs right before I picked the car up, but that's nothing new is it...? Other than an overwhelming exhaust smell I was blaming on the Edelbrock Performer carb the car ran ok. The black RTV that was used did nothing to stop the intrusion of the oil into the heads and was doing it for awhile by the looks of the valve stems. The Permashield seems like it would be ideal since it's the only one that specifically states it's fuel resistant but it's not really a sealant so don't know if it would be of any value on metal to metal. Maybe all that is needed is a thread sealant...
