You can either run a ZDDP additive to conventional
oil or even better, just run an
oil like Valvoline VR-1 Racing or Brad Penn that still has the higher levels of
zinc. But do one or the other before running the engine.
Search "
zinc" here as this has been discussed ad nauseum.
And by the way, to the comment above about
zinc not adding much to an engine already broken in, this is NOT the case with a flat tappet. You really need to run an
oil with elevated levels of zinc for the flat tappet and solid lifters.
