Description
Graphited head gasket to suit P55 and P66 engines with thermostat.
Note that on later Engines, Stuart removed some of the water jacket holes in the head gasket. Since engines would be mounted in on an incline (to align with the propeller shaft) and cylinder 1 (flywheel end) would be uppermost and number 2 cylinder would cool fine without the additional ports. The end of this gasket with the most water jacket holes should be placed at Cylinder 1 (flywheel end of the engine). Or cut additional holes with a sharp knife or gasket punch.
