For the 4AG engine, two types of head gasket structures are available depending on the model.

BEAD TYPE The bore circumference, coolant and oil seals are all sealed well with the bead confifuration.

■ Heat Conductivity & The Strength of Stainless Steel

Stainless steel was chosen to be the material of choice to make the Metal Gaskets with because of the heat conductivity efficiency of the stainless steel material to evenly distribute the heat and aid with cooling. This will greatly improve reliability and reduce the chances of problems.
The natural high tensile qualities of Stainless Steel greatly helps with increasing the joint ridged of the cylinder head with the cylinder block. This helps minimize the engine from warping when under severe stress loads that performance engines go through when running high power applications. The result is improved durability and added power gains.

■ HIGH SEALING PERFORMANCE

Optimum design of the bead line securely seals the water and oil lines.
