I did it with a 318 years ago with short hours on it. Can't remember the reason but the heads were peeled of the engine and slapped on another and I just sprayed the (permatorque) gaskets with gasket sealer and screwed it together. If was almost done as a goof, lets try this and see what happens.

Engine ended up being in THREE different vehicles before I lost sight of it. Came out of my Dart where it ran low 14's on street tires, sold to a buddy who installed it in his ramcharger and then ended up in a 77-78 Snow Commander plow truck at work.

The truck actually ran better with the 318 than it did with the 360-2 that was in it before.

When I left the job the truck was still plugging along if rotting apart at a good rate. Engine never gave a problem.

If that gaskets didn't stick to the head or deck I'd consider re-using them.
