What is the best head sealant out there
 

I think I have a leaky head and need a sure fire sealant to fix it. Any suggestions...?

I have used Seal-All Polymer Sealant successfully in the past. Clean the cylinder head, pour it in the water jacket to fill it up to coat the inside of the water jacket and put it in the oven at the recommended temperature. It leaves a rubberized coating inside the water jacket.

I have fixed a few with Envirotex. It’s the stuff they use on bar tops and tables. You can get it at the craft shop. Clean it good with some purple cleaner then dry it pour the epoxy in and rotate the head to the position that the epoxy will get to the suspected area that you think the leak is. Works good. If you can find the leak welding is best.
