* A set of rocker arms and shafts
* A set of push rods
* A rocker arm installation tool
* A torque wrench
* A straight edge
* A feeler gauge
Install the rocker arms and shafts.
1. Begin by lubricating the rocker arm shafts and the push rods with engine oil.
2. Install the rocker arm shafts into the cylinder head. Make sure that the oil holes in the shafts are aligned with the oil holes in the cylinder head.
3. Install the rocker arms onto the shafts. Position the rocker arms so that the push rods are seated properly.
4. Use the rocker arm installation tool to install the rocker arm nuts. Tighten the nuts until they are snug.
Install the push rods.
1. Position the push rods in the push rod cups on the rocker arms. Make sure that the push rods are fully seated in the cups.
2. Adjust the pushrod length. There should be no more than 0.025" of clearance between the push rod and the rocker arm tip. Use a feeler gauge to check the clearance.
Torque the rocker arm nuts.
1. Use a torque wrench to tighten the rocker arm nuts to the specified torque. The torque specification for Chevy 350 rocker arm nuts is 20-22 lb-ft.
2. Recheck the clearance between the push rod and the rocker arm tip. Make sure that there is still 0.025" of clearance.
Check the rocker arm geometry.
1. Use a straight edge to check the alignment of the rocker arms. The rocker arms should be parallel to the cylinder head.
2. If the rocker arms are not aligned, you will need to adjust the push rod length or the rocker arm height.
Install the valve covers.
1. Place the valve covers over the rocker arms. Make sure that the valve cover gaskets are seated properly.
2. Tighten the valve cover bolts until they are snug.
Start the engine and check for oil leaks.
1. Start the engine and let it run for a few minutes.
2. Check for oil leaks around the rocker arms and valve covers. If you see any leaks, tighten the bolts until the leaks stop.
