[QUOTE=1971BB427;1798657]I think you'll be fine without any additive to oil, but that depends on your oil of course! Too much zinc is bad also, so don't go overboard on breakin oil or additives!
X2! Dont read to much into the whole oil thing. I've done many non roller engines that have gotten lots of miles with no camshaft failures.
No doubt roller cams are the best.. But the Hyd and solid cams have they're place also. I do use some additive for break in but after the drain and refill I've never used any more additives.
