Cylinder Head Gasket; 4.0 in. Standard Bore; Competition Gasket For Cast Iron Or Aluminum Heads; .042 in. Compressed Thickness
Ford Racing performance cylinder head gaskets minimize blowout and have a wire-ring combustion seat for extra sealing around combustion chambers. Ford Racing performance cylinder head gaskets are available with either steel-core laminate construction for cast iron heads, or graphite cores with a pre-flattened steel-wire ring, so they won't brinell aluminum heads.
