Lube on cam and lifters.

do not zddp to SN oil
Isn't that backwards? I thought the newer SN has the low ZDDP levels under 900 PPM (at least for the lighter weights 30W and lower).

OP, prime the engine as suggested. I personally prefer a moly loaded cam lube like the old Iksy cam lube; there are others. And as said above, putting a generous dab of the lube on the bottom of the lifter is sufficient; after the first full rotation of the cam, it is all wadded up under the lead side of the lifter anyway.
