Valve Train

Motion is transmitted from the camshaft, through the hydraulic roller valve lifters and tubular pushrods, to the roller type rocker arms. The nylon valve lifter guides position and retain the valve lifters. The valve rocker arms for each bank of cylinders are mounted directly to the cylinder heads. Each rocker arm is retained to the cylinder head by a bolt. Valve lash is net build. The exhaust valves have sodium filled valve stems. The intake valves are a titanium design and have a rocker arm wear pad at the top of the stem.
