New to me 426 hemi oil question

[Petroleum1]

The car was serviced before i received it but since i could not verify what type oil was used i changed the oil to my fav which is the valvoline 20-50 ZR1 with zinc. Since i am new to owning this fabulous 1968 hemi engine i was wondering if i need to add any zinc to the mix or just run with what is in the racing oil. Tia
