Second the Camsavers, I also use Sealed Power on the mild ones like that, but not sure I'd even do that after using the Crowers.
The Summit stuff scares me, I had a single cam go flat on me in as long as I can remember, Summit cam and lifters, and although we found the spring pressure on the "pro-built" heads (nobody here BTW) was much higher than what the sheet said, it likely could have lived the way I fired it on the stand. I can't specifically blame the Summit parts because of the high spring pressure, but they didn't help either
