Can/should you re-use engine components?

3k and it's not reused? C'mon man... should last 125K.

I have a used timing set that I'm using in my race motor. No idea what it came from. Doesnt matter... it's in good shape and I will use it.

Pretty obvious none here worked at a dealer... we used to have to reuse head gaskets on Chevy and Mopar warranty work. Clean them and use Permatex #1... never an issue. That was in 1967-1972.

I had a Cloyes chain from 2019 in my 340 for about 20 hours. Stretched wider than a..... changed to Pro Gear, have about 10 hours on this chain and so far so good...
