[QUOTE=vettenuts;1574949507]To the OP, the lift of your cam has me very suspicious it was a Crane grind and not a Comp. All the Cranes used 0.551" lift on the lobes. QUOTE]
It might be crane, I can't find any evidence for why I thought it was comp.
I guess I'll plan on ls6 cam with ls6 beehive springs and ls7 lifters.

Mike is spot on with his suggestions in using current stock LS6 springs with a stock cam. It is a myth that the stock ones will fail. There were issues a number of years back, they have been corrected and the current springs are fine.
If the OP wants to stay with stock size cam, buy it from any of the forum supporters that sell the GM Performace products. The cams are process checked to meet hardness and other requirements.
