not exactly cam related, never did light spring thing on my motors and never had any trouoble even with high lift racing cams and springs, just an anecdote that maybe applies. udo gietl, tuner of the AMA winning R90S beemers would build his motor DRY, put one drop of oil in the bores and start his engines like that, the idea was to use the still sharp machined surfaces to grind rings and everything else into full contact.
last fresh motor i did was put on dyno immediately (no idling) for 5-6 3/4 throttle pulls and then oil change. motor runs like a champ still after 30 something race weekends.
"Gietl examined the break-in process. He decided that the familiar cross-hatch hone pattern left by proper cylinder preparation is nothing but a one-time double-cut file to shave the rings into intimate contact with the wall. Once break-in was complete, the wide ring contact would be lubricated well enough to glide over the hone pattern, which would have worn down almost completely anyway. He reasoned that too good an oil film could stop the break-in prematurely. He therefore adopted a dry break-in procedure. The pistons, rings and cylinder bores are solvent- cleaned and assembled dry save for a drop of oil on each piston skirt. The engine is started and run at half red-line for nearly a minute. Upon teardown, the rings were seen to have seated very nicely."
