Should I rebuild a "good engine" to fix oil leak?

Peace of mind...Pull the engine,replace all gakets and frost plugs.While it,s out and the oil pan off,I,d also replace the timing chain and gears.I,d also replace any rusty exhaust studs.Some fresh engine paint and re-install.you,ll be glad you did this in 5 yrs.This is just what I,d do.:D
