SBC leaks

Jeff,

Go down to the local craft store and get Envirotex. It is the 2 part epoxy they use to pour bar tops. I just fixed my heads that had the same problem. I welded the crack in the spring pocket. Then I cleaned the water jacket using Castrol Purple cleaner. Let that dry real good. I force dried the head with a small heater. Then turn the head over and pour the epoxy into the water jacket. I had to put some tape over the water inlet on the manifold side to keep the epoxy from running out. When you get the head in the right position you should see the epoxy starting to come out where the crack is located. I let the epoxy cure for a week before starting the engine. No water in the oil at all.
