Good To Know

Q: What does a top end gasket set include? A: It typically covers the gaskets and seals for the cylinder and cylinder head mating surfaces, which are replaced during a top end rebuild. Q: Can I reuse old gaskets? A: No, top end gaskets are single-use and should be replaced each time the cylinder head or cylinder is removed.
