Dave, good to see you're still around and didn't give up on the vehicle. And congrats on getting it done in a day after such a long hiatus from the engine bay.
On the slanty engine, I believe thats just how it sits. The engine does have a slight rear dip, plus the hood slopes down rather dramatically.
The lack of intake manifold peobably exaggerates the gap, so let's see how it looks afterwards.
Here's an old picture. See how close to the brake lines and vent plug the rear is. I'll try to take another from the side, but IIRC, the front of the engine is high enough I once left a tool on the little engine cover and it left an imprint on the hood insulator.
