Specs At A Glance

Good To Know

Q: Does this gasket require new head bolts? A: Many manufacturers recommend inspecting or replacing torque-to-yield head bolts during a head gasket job, so check your service manual before reinstalling. A: Reusing worn bolts can lead to uneven clamping and premature gasket failure.

Q: Should I resurface the head before installation? A: If the engine overheated, having the head checked for warpage and resurfaced if needed helps the new gasket seal properly. A: A clean, flat mating surface on both the head and block is essential for a lasting seal.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
