What is Hyper "E" ?
So far, the only difference I have noted between the 2 makers of the slugs are the amount of silicone content there made with. Difference in slugs construction that is.
Rob the reason you have to gap the top ring wider on the KB's is they moved the top ring farther up on the piston exposing it to more heat so the gap closes up more when hot. I saw one come out of an engine that the guy didn't gap them wider and it wasn't pretty. Snapped the top of the piston right below the top ring.
