I could use it as a precaution but the metallurgy of Buick heads does not really require it. I do run a cleaner for the valves through the fuel tank once in a while. By and large, the issues with the 264 nailhead were completely created by the rebuilder. Further, the thermostat installed let the engine run much to cool and allowed incomplete burn of fuels and other crap the previous owner was dumping in the tank. As you can see from the pictures, the carbon and oil in every cylinder looks like the La Brea Tar Pits. Since my repairs I driven the car 1000 miles. The piston rings have seated well. No oil loss. I pulled the plugs and all look as they should with complete burn of fuel. She pulls like a freight train.
