    Rated 5 out of 5 by from They do what they say. I bought these to use on my jet-boat. Sealing the snail style exhaust manifolds has been recurring issue on my BBC power plant. Earl's Header Seals did the trick. If I put my ear near the valve cover, all I hear is the sweet sound of valves opening and closing.
