What's the best oils for tappet cam engines?

That's a 2009 article,Rotella has since changed. Most,if not all of the zinc has been removed from it.There is also debate on whether zinc is needed at all,after break in.
To be on the safe side,chose your favorite oil,with your favorite zinc additive.

Mobile1,Valvoline,Castrol,all good choices for oil.
GM,Comp,Lucas,etc for zinc additive.

Then there is special racing oil,that still has zinc in it. The bottle usually says off road only.
Brad Penn,Comp,Joe Gibbs come to mind.

Next question is, synthetic or conventional.....:D
