Stock roller lifters are almost guaranteed to be superior quality in this day and age compared to most aftermarket stuff (especially Comp). I reused the factory roller lifters in a 5.9 Magnum short block I pulled from a junkyard 2000 Dodge Ram 2500 with high miles (at least 150k) with a custom-grind Racer Brown camshaft. Been running that way in my '70 Duster since 2017, put maybe 15k rowdy miles on it so far including some autocross fun and a few passes down the drag strip. Zero issues.
If it were mine I'd reuse stock lifters and have the stock cam reground, like others have recommended. Several members here have done that with great results. I've never heard of lifters failing in stock roller cam LA and Magnum engines. Metallurgy and tolerances of OE American engine parts in the late 80s-90s was excellent.
