Assuming you don't have a cooling system problem...

If you have distributor vacuum advance taken off the port on the
carburetor,  plug that up and take it directly off the manifold
vacuum. You'll have to re-set the idle. It will run a lot cooler.

Ported vacuum lowers idle NOx emissions by lowering combustion
chamber temperatures -- but it does this by making all the heat
go into the head, to heat the water!

Drive it! A primered Jav is still a 34+ year old cool car!
