The good reports and opinions are for the Lion 3. I had a discussion with a friend who has a Lion 3 and he is happy as is hardtimes. I may call Charlie Yapp soon to discuss. At this time, it looks like I have some overweight & not good brand new heads. Anyone out there want them?

Vic, look at your head and see if the spark plugs are not located over top of the Pistons (instead of the valves). Also look at the combustion chamber and see if the edges are sharp. Also, check your PM.
