The tough construction of these Sinister Diesel head gaskets includes 5 layers of stainless steel sandwiched, creating an heavy-duty seal for each cylinder, despite extreme compression and heat. Each gasket is also coated with fluoroelastomer (FKM) to prevent the flow of fluids past the gasket, ensuring a secure seal between the cylinder head and block.
