Would need to replace cam, lifters, pushrods, rocker arms; what else?

Everything else is the same. I once had to use mechanical lifters on a hydraulic cam and it made a huge racket. So I adjusted the valve lash down to 0.002" and adjusted them about once a week to be on the safe side. Eventually, I got time to swap to a mechanical cam and all was well. This was back in the day when parts were readily available.
