Does it always run that temp or does it run cooler (or hotter) around town or on the open road? This can help isolate the problem as being a lack of airflow or coolant flow, etc.
First be sure the temp gauge is reading correctly. Use a temporary mechanical gauge to check it.
Be sure the thermostat is working as it should. If you have a clutch fan, check it for correct operation as well. Be sure there's no belt slippage- sometimes you won't hear the belt squeal. If you have a flex fan, they can cool poorly. You also need a shroud that fits the fan assembly.
is some info on the divider plate that could help you. No rust holes allowed!
Also be sure the sleeves/grommets are in place correctly.
You should check the ignition timing to be sure it's not retarded. This isn't usually a problem, given the low compression of the stiock Pontiac engines from the smog years, but it's still worth checking.
