You'll need a powerhead gasket set to put everything back together after breaking down a power head to work on changing pistons, connecting rods, bearings, and other internal engine components. Please keep in mind that some powerhead gasket sets include a head gasket while others do not. Gaskets for everything attached to the main engine block, such as the thermostat cover, water jacket, exhaust housing, powerhead base, carburetors, air silencer, and so on, are usually included in sets. Each item meets or exceeds the original equipment manufacturer's requirements. Because it is highly durable and less prone to breaking, it has a long service life and is less likely to break.
