Hi,
When you tighten the intake, make sure to follow the sequence and do it in two steps. As far as the rocker arms are concerned, when you torque them, make sure the camshaft lobe is not touching the rocker.
Last, the cylinder heads are to be torqued in sequence and in three steps. First, you will reach a specified torque. After that, the bolts are turned in degrees.
Let me know if this helps or if you have questions.
Take care,
Joe
See pic below. Noite: The last two pics are for the rocker arms. Also, note that the intake is torqued in inch-pounds and not foot-pounds.
