(Formerly "ICS Titan") Patented Integral Combustion Seals perform the function of O-ringed blocks and heads without the added machining costs. They also provide extra sealing in high combustion pressure environments where rules prohibit O-ringing. The ICS features stainless steel O-ring wire inserted into the gasket body around the cylinder bore, with combustion pressure forcing the flanges against the head and block for a self-energized secondary seal. Coolant and oil seals also included.
