OLDSMOBILE 455 V8 4.320 X .062 ICS TITAN COPPER HD GSKT

These copper gaskets feature patented integral combustion and coolant seals, eliminating the need for additional sealants for user-friendly installation and reliable fluid sealing. The fluid seals are bonded to both sides and offset to allow the annealed copper to deform for a better seal and to prevent blowout. The built-in combustion seals on ICS Titan gaskets replace O-ringed blocks or heads, enabling the use of power adders or extreme compression ratios. The gasket body is split at the bore opening to accommodate a stainless wire O-ring primary seal, with upper and lower flanges creating a secondary combustion pressure seal.
