Engine Bay Restore or not?

I'm at the stage of should I restore the engine bay of my 72 Swinger or leave it original.

It's a 37,000 miles original car and the only thing I have done is a recent respray of the exterior, new vinyl top & tires.

The rest of the car is unmolested, original condition.....

The original PO had poorly painted the engine. Why, I have no idea!!

As the saying goes, "It's only original once"

So, I need a vote....
