Fitment & Technical Details
Inspect the valve seats, guide bores, secondary air injection port, and deck mating surfaces for absolute cleanliness prior to installation. Ensure the cylinder block upper deck is completely flat and free of old gasket carbon. Torque the cylinder head bolts in strict sequence and specified stages using a calibrated torque wrench, followed by precise valve clearance adjustments.Verification: Matures a leak-free seal across the combustion chamber and secondary ventilation channels, maintaining correct valve train geometry and compression under high operating temperatures.
