CYLINDER HEAD ASSEMBLY AND INSTALLATION
1) Install the valves, then turn the head over to install the stem seal on the intake valve. Note that the
flat end of the seal faces the head.
2) Install the valve springs and retainers.
3) Position the head plate (H) with tangs facing down (inset). Install the two studs (I) and tighten them to
125 lb-in (14.1 Nm).
4) Place the head gasket on the cylinder. Ensure the breather hole in the gasket aligns with the
breather hole in the cylinder.
5) Install the head assembly to the cylinder with four screws. Tighten the screws to 210 lb-in ( 23.7 Nm)
in the sequence shown.
6) Install the push rods and the valve stem caps.
7) Install the rocker arms and the rocker ball nuts. After setting the valve clearance (see Common
Specifications chart below), tighten the rocker ball nuts to 70 lb-in (7.9 Nm).
8) Place the cover gasket inside the valve cover and fit the cover over the cylinder head. Install four
screws and tighten to 80 lb-in (9.0 Nm) in the same sequence as the head screws.
