HEAD GASKETS, Titan Self Sealing Copper, fits Mark 4 Chevrolet Big Block BBC. Bore Opening: 4.320"; Gasket Thickness: .043"; Package Contents: 1 Pair; Material: Copper with built in coolant and oil seals.
*These Gaskets are to be used with machined O-rings in Block or Head*
*For competition engines which are not O-ringed please see ICS Titan*
*These Gaskets do not require additional sealant*
Patented coolant and oil seals found only on SCE Titan and ICS Titan head gaskets provide superior sealing due to offset upper and lower bead seals and limited sealant area. This unique seal design requires less clamp load to seal coolant passages allowing more clamp load on the combustion seal than other "coated" copper gaskets.
