The rockers are zero lash, When you find out what length push rods you need heres the proper way of torquing the rocker arms.
The Number 1 piston is at the compression stroke when the Number 6 cylinder inlet and exhaust valves are rocking, that is when the exhaust valve is at the end of its upward travel while the intake valve starts its downward movement.
Rotate the crankshaft until number one piston is at top dead center of compression stroke.
With the engine in the number one firing position, tighten the following valve rocker arm retaining bolts. Tighten exhaust valve rocker arm retaining bolts 1, 2, 7, and 8 to 30 Nm (22 lb ft) . Tighten intake valve rocker arm retaining bolts 1, 3, 4, and 5 to 30 Nm (22 lb ft) .
Rotate the crankshaft 360 degrees.
Tighten the following valve rocker arm retaining bolts. Tighten exhaust valve rocker arm retaining bolts 3, 4, 5, and 6 to 30 Nm (22 lb ft) . Tighten intake valve rocker arm retaining bolts 2, 6, 7, and 8 to 30 Nm (22 lb ft) .
