SCE-S11066 - COPPER HEADGASKETS ICS SBC 4.060 .062 pr

ICS Self Sealing Copper Head Gaskets fit Chevrolet Small Block SBC. Patented Integral Combustion Seals found only on ICS Titan head gaskets take the place of O-rings in the block or head, with an added benefit. The upper and lower flanges of the ICS combustion seal remain open toward the cylinder allowing the pressure of combustion to force them against the block and head.

Extreme cylinder pressure can cause the head to lift, in this case the upper and lower seal flanges trap high pressure gases forming a secondary combustion seal. Coolant and oil sealing is handled by exclusive patented bead seals bonded to the gasket surface.

NOTE: When determining gasket bore opening consider the combustion chamber shape to insure that the combustion seal falls outside of the chamber.
