Well bro, In my opinion, if your mechanic is a reasonable + an expert, you can hardly find differences in an original engine & overhauled engine, just a little bit sound is increased if the engine is not sealed or overhauled engine,
In easy words,

just 2 weeks ago, I have a coure 2004(now its sold), its engine is overhauled after 170k +km, due to a poor oil change, the oil decreased its minimum level & the car badly smoked, before that the car is 100% genuine & it went on a no. of long trips all over Pakistan,
after overhauling the engine, the car was fine again, just like new, it costed 18000 including all genuine parts+oil, pick was just like before,
I was satisfied 2 weeks ago, don't know how its kept nowadays as I sold it on an above market offer:)
A 1999CIVIC engine can be overhauled in 12k,13k by an Anari, while the same engine by an expert will cost minimum 30k+ including parts etc(Its my experience)
