Features:

• Fel-Pro Performance head gaskets accommodate the high cylinder pressures and cylinder head movement associated with performance engines
• Inserted within a stainless steel armor surrounding each cylinder, wire ring design provides highly concentrated sealing around the combustion chamber
• Raises combustion sealing force to roughly three times that of standard head gaskets
• Copper wire rings to essentially eliminate head brinelling and bending
• Not intended for use in emission controlled vehicles
