My opinion is...if it oils...that's good. The oil pump can supply the "slow" rockers.
Free advice......IF possible get a carb you KNOW has worked on a running engine.vs one that's brand new and never supplied fuel.
Make sure the carb bowls are full of fuel.
Double check firing order and wires. (yeah...I know...check'em anyhow.)
FULL battery charge.
Fire exstingusher handy
Fire it OUT SIDE the garage(not inside!)
Check oil level
Confirm absolute TDC with a TDC tool. Mark the balancer.
Advance timing to about 6/8* and leave the hold down bolt loose so you can turn it.
Have a helper....one to crank and the other to work the carb and timing.
I like to spray starting fluid in carb (with butterflys open) BEFORE cranking.
DON'T stick your face over carb while cranking!
