Sealing the cylinder head to the top of the engine block is the head gasket. This critical component is responsible for preventing any oil and coolant leaks, as well as keeping compression within each cylinder during combustion. Let Aeroflow Performance supply the very best in head gaskets for your engine rebuild to provide the most effective leak free seal between your engine block and cylinder head. Available in a basic graphite single layer head gasket designed for an OE factory replacement engine. For high performance engines we recommend the multi-layer steel head gasket. These are constructed from multiple layers of stainless steel for strength and contain load-controlled embossments that conform load distribution across the sealing area.
