Hold up, you were told "no lash on a solid roller cam"? Yikes, that's BS. Please add .020 lash hot on both intake and exhaust!!!! That could be your 'running like **** warm' as the rollers at .010 or zero are holding the exhaust valves open! Comp Magnum solid roller cams spec to .020/.020 lash, I assume that would be a good start and a roller is pretty tolerant of a wide lash.
