You can use a Spacer. But first...

Is the gap between the Heads and Intake manifold even through out?
If it's not... more than likely your Cylinder Heads has been angled milled (This is when more material is milled on the Spark plug side of the Cyl Heads.)
If this is the case, either the spacer or the manifold will have to be machined first for proper fitment.

It looks like the gap is even on both side.
You will need a spacer with a (correct thickness for your engine)... like the ones below if you want to use that Cylinder Heads.
This one is from Dart... there are other makes too.

I would recommend checking the Distributor installed height after, just to make sure proper Cam and Distributor mesh is okay.
Good Luck!
