Guide? Not likely but it's pretty straight forward.
Remove the intake manifold and fuel rail, remove the rear coil packs and slide the harness out of the way. Remove the rear valve cover, then remove all the bolts for the rocker arms. You can remove the whole rocker arm rail in one piece, then remove the pushrods one by one and label them to have them go back in the same hole. Then remove the exhaust manifold bolts to the cylinder head. Remove the bolts that hold the cylinder head to the engine block and lift the head off the motor.
Under there is the lifters and lifter trays.
I forget on a LS4 if the power steering pump is bolted to that cylinder head or if any brackets are bolted to the head on the serp belt side.
