wherever you see injector that is intake others are ex.
Intake push rods are 5 and 3/4 in long
exhaust push rods are 6 in long
torque for rocker arm bolts =124 inch lbs
lower intake tightening sequence
8 4 2 6
7 3 1 5
on the first pass in sequence tighten them all to 62 in lbs
then 1 2 3 4 in sequence to 115 in lbs on the final pass
and 5 6 7 8 in sequence to 18 ft lb on the final pass
upper intake plenum junk yards sell for 25$ but I would not worry since other bolts will be more than enough. just put some hight temperature gasket sealant around the bolt opening just to prevent any leaks (just in case)
anything else just ask
