Ensures no leaks, due to a perfect fit of all cylinder head components and mating surfaces. This provides maximum reliability and longevity. Clean. Casting processes can leave behind core sand deep inside cylinder heads which later serve as harmful contamination to the engine or prevent proper cooling during operation.
