NG or NF? The head from an NG won't work with your CIS. The NG had injectors
in the head and the NF had injectors in the manifold (or do I have that
backwards?)... Either way, NG heads are not compatable with the CIS systems
of cars that did not come with a NG stock. I think what you need is a NF.
One other thing to check...air in the cooling system can cause pressure
build-up like you describe. Try bleeding the radiator...
