Is Moroso A-B epoxy good stuff? Anything better?

You are in luck! I just finished smoothing out the epoxy, I spent at least an hour with brake cleaner, small wire brushes, toothbrushes, purple clean, sandpaper, etc making sure I got the surface clean. I am just cleaning and inspecting the head, valves, etc, hope to have it all together this afternoon. I will snap some pics here in a bit of one of the untouched heads inthe basement, and some of the head with the epoxy. I would like to experiment someday with tubes, but these are for a friend, so I didn't want to go too overboard. Well, I guess I already did haha, but I wanted to use as little epoxy as possible.
