Please help my dual powered 390

Just had the radiator repaired after a bad session of overheating, now its missing on a couple of cylinders, coolant is disappearing and there is a fine film of gunge around the neck of the expansion tank. Gut feeling says head gasket. What is this gonna cost to get fixed?

Thast doesnt sound good, you should get one of those water testers for hydrocarbones leeking through from the head into the coolent, the water with change colour if it detects hydros.
I think you can get these from all good motor factor shops.

You could get it pressure tested for leeks on the water side and also do you cylinders too for compression, if all are with in say 10 psi your heads are ok, if one is very low you have a prob with head.
Hope this helps
