The Chevrolet 350 engine (1967-2003) uses adjustable hydraulic lifters that are individually adjusted by means of the rocker arm nut. The rocker arm nuts are not torqued down. Typically the rocker is tightened down to 0 lash then the rocker nut is turned in one full additional turn.
The head bolt torque, on a 3304 Caterpillar engine, is 350 pounds per square inch. The valve lash should be adjusted to .023.
