Overview 

The Siruda head gasket for the 1FZ engine, with a 101.5mm bore and 2.00mm thickness, is a high-performance sealing solution engineered for engines running elevated boost, compression, or experiencing deck machining. Built using premium multi-layer steel (MLS) construction, it provides excellent sealing integrity under extreme temperature and pressure conditions. The 2.00mm thickness is ideal for custom builds where piston-to-head clearance, altered compression ratios, or deck height adjustments are factors. This gasket is designed to withstand high combustion loads, reducing the risk of head lift, coolant leaks, or gasket failure. Its precise fit for 101.5mm bores ensures reliable performance in both racing and high-output street applications,
