Gap in heater core inlet/outlets. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a non-A/C truck.
There is a gap about 1/4 inch on both the inlet and outlets between the tubes and the heater box.
Has anyone filled this gap to "dress things up" under the hood?
It looks like there should be a filler off putty there, and it would look a lot "cleaner" if there was.
I'm think about using a black plumber's caulk. It's semi permanent, and sets up with a flat finish.
Did these trucks come from the factory with this gap? Or was there some sort of gasket/filler putty there?
