What kind of oil should I put in my Evo?
I would just go with a good quality dino oil in the EVO. I run synthetics in my twin cam, but my 93 evo is just fine with dino oils. I put 62,000mi on my 94 EVO before I did a top end job. And put another 74,000mi before I sent it off to the reman. program at HD.
How to tell if your Harley Davidson has fossil oil?

Is the bottom end of an Evo bullet proof?
As the fine gents said. I can only add that the EVO bottom end is mostly bullet proof, in particular late EVO’s.

Where can I get parts for my EVO engine?
