****84/85mm copper spacers OUT OF STOCK****
****86/87mm copper spacers IN STOCK(one left)****
Our proprietary copper head gasket spacer is used in conjunction with an OEM or Cut-ring head gasket to lower the compression for forced induction on a stock bottom end (Not needed for low compression motors or NA applications). Our copper head gasket spacers have sealant embossed to the block side of the spacer to eliminate small coolant leaks caused from block surface irregularities. Add an ARP head stud kit to complete the package!
We highly recommend 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.
