Make sure you label every connector on the harness. You will thank yourself later. I did label most but not all and I thought "I can remember this", but weeks, months later I just had a blank stare when looking at them again.
LIke Karter said, I would change out the timing chain and gear set. It's easy to do now and doesn't cost that much. There are great videos on from Cloyes on exactly how to do it. Don't forget the chain tensioner. And be careful how you engage the chain tensioner. I thought I had it and then double-checked and I didn't!
