Ultimate head gasket for forced induction S54 engines. These feature an organic gasket combined with a metal cooper ring/cut rung around each cylinder for an unbeatable seal. Combine this gasket with one of our ARP head bolt sets for a bulletproof gasket solution. Does not require any additional machining for the cut rings (unlike o-ringing). The latest version of this head gasket includes newer style cut rings that have a triple groove cutting surface for maximum sealing. 87.5MM bore, 0.048" thick.
These gaskets require a retorque after the engine has been heat cycled. If you have a question please shoot us an email and we'd be glad to help. These parts are not always in stock as they are low volume items and we purchase them in batches. Please email for estimated ship dates if it is a time sensitive purchase.
