Two quick things. Pardon me if they've been mentioned. Make sure during cam and/or rocker break in to use additional zinc. I have a racing cam that looks like that. For almost ten years, it has been my best cam. It hasn't gotten worse so I just just say there's less parasitic drag since there's less surface area. Hah!

The car is finally running and I've broken in the cam properly, running the engine at 2 - 3k rpm for 30 minutes.  I am using Brad Penn (PennGrade) 30 wt. break-in oil.  At 100 miles I'll switch to PennGrade 10w-40 or the oil combo that Rebello recommended.

 

 

 

These were taken just after the 30 min break-in cycle:
