Lifter replacement

This engine is not broken in. 30 min run time total. Would the Rislone or maybe Marvel Mystery Oil hurt the engine at this time? Some more info. 318 block with factory 360 heads, rockers, shafts, pushrods, and valve covers. I just pulled the left side valve cover. I could turn half the pushrods by hand. The ones that turn are not pumped up, correct?
