All you need is an Autozone hi flow p/n 15356 160 degree thermostat. PERIOD!

Also, base timing should be adjusted so you have a total timing of 36-38 degrees...with the vacuum advance disconnected and hose plugged.

With a GM factory style shroud, a 7 blade clutch fan, proper timing, and the stat mentioned above you will NEVER have any overheating issues.
