New lifters on a used cam is inviting disaster these days. Or even changing cam/lifters to a different block. I have a customer that installed a slightly used cam and lifters (less than 1000 miles). From his old engine. Into a new engine for his street only ElCamino.
Lifters were marked to the lobe and assembled with break in lube and zinc supplement in the oil. Valve springs set at 95 lb. on the seat. Roller rockers.
The engine wiped all but one lobe off the cam in two weeks time. .
