Depends on the camshaft type (roller or flat tappet), lifter type (hydraulic or solid), bearing manufacturer etc.
Oil pump driven gear type (on distributor) and inspection is also a factor.
Carbon buildup, ring gaps increasing, bores wearing etc add up to efficiency loss.
When you feel the power is down a bit, a "freshen up" is probably due.
