Oil Weight for 1951 288 that had rebuild 20-25 years ago

Car didn't have oil filter canister when I got it. I used 30W conventional (no additives) at first. Next I used 30W Valvoline VR1. Local classic car shop recommended 10W-30 so I bought Lucas 10W-30 Hot Rod oil. Haven't put it in yet. I think many here would suggest 30W but is that for an original engine? What about an old rebuild engine?
