For the oil, to get adequate zinc I run diesel engine oil in my flat tappet. Shell Rotella T. Another option is dedicated classic car oil with higher zinc like Joe Gibbs. Yet another is standard car oil with a zinc supplement like Comp Cams break in supplement.

If you are worried about the cam, probably best to pull the intake, roll the engine over and have a close look at the lobes. Only because cam failure can create debris and collateral damage. I would add that an engine with moderate cam already broken in may not be as sensitive to lube oil. New cam/new lifters can be quite sensitive.
