engine level?

So im finally getting my 408 bolted in for the last time, and have a silly question..
When I put a level on my oil pan it seems level but across the valve covers its slightly low on the passengers side. Should it be sitting level across the valve covers? I do have the car sitting level.

It doesn't matter that much, but if it bugs you like it would me you can space your motor mount as long as it doesn't cause other problems somewhere else.
Biscuit style mounts can take a spacer plate, and spool mounts are easy.:D
(Just loosen the big through bolt and lift the motor a little, then tighten it back up.)
