1. Remove any labels used on the hydraulic lifters. Apply a thin film of SCREAMIN’ EAGLE ASSEMBLY LUBE to outer surface of each lifter. Pour a small amount onto each cam lobe.
2. Install lifters in the crankcase bores with the oil hole on the inboard side and the flats on the lifters facing forward and rearward. To avoid damage, do not drop lifters onto cam lobes.
3. See Figure 3-80. Place the anti-rotation pin (4) on the machined flat between the blocks cast into the crankcase.
4. Install new O-rings in the lifter cover bores and the cylinder head pushrod cover bores.
NOTE
During cover installation, verify that the anti-rotation pin (4) is held in place by the ribs (3) cast into the inboard side of the lifter cover. Movement or loss of the pin can result in lifter rotation causing engine damage.
5. Install the lifter cover (1) and new gasket (2). Install four socket head screws. Tighten the lifter cover screws to 100-120 in-lbs (11.3-13.6 Nm) in a crosswise pattern.
6. Install pushrod covers.
a. Assemble pushrod covers with new O-rings.
b. Hand compress the pushrod cover assembly and fit the pushrod cover into the lifter cover bore.
c. Extending the assembly, fit the pushrod cover into the cylinder head bore.
d. Do not install the spring cap retainers at this time.
NOTE
To install spring cap retainers, see 3.25 TOP END OVERHAUL: ASSEMBLY, Rocker Arm Support Plate.
7. Apply a small amount of SCREAMIN’ EAGLE ASSEMBLY LUBE to the ends of each pushrod.
8. See Figure 3-81. Install the pushrods. If installing original parts, install them in their original locations and orientation. Always remove any tags that may have been used for identification.
