Steve, my Crower cam is part number 16462 Street Roller Performance Level 4, requires kit #84524 which specifies lifter, springs, retainers, and seals. This cam and kit are good for 7k rpm in an FE. All are viewable at:

FYI, the tan smoke you saw from my exhaust during warmup was leaded race gas deposits on the inside of my pipes.
Hope that helps.
