Grade 3 Performance M.L.S. Head Gaskets to suit all Toyota 1HZ, 1HZ-T and 1HD-T engines.
Engine Australia has worked with Cometic Gaskets to develop these Performance head gaskets.
When used with our ARP2000 head studs there is more control of cylinder pressures by less head lift and better combustion chamber sealing.
