Bent up stuff
I hate to say it, but that seems pretty careless for a machinist. Even the best guys screw up sometimes but none of his work was up to par. I feel for ya and I'm confident you'll get everything sorted out. Right now I'd say you've already got a better understanding of valvetrains than he did. Some of the guys have provided links to good information that should help out even more. If you're in doubt about anything there are definitely guys here that can help.
