WARNING: This engine uses "Torque To Yield Bolts". Always use new cylinder head bolts to ensure leak-tight assembly. Torque retention with used bolts can vary, which may result in coolant or compression leakage at the cylinder head mating surface.
12.Reverse procedure to install, noting the following:
a.Lightly oil all bolts except short ones.
b.Apply suitable sealer to short cylinder head bolts.
c.Using tightening sequence shown in Fig. 7, torque cylinder head attaching bolts in steps as follows:
1.50 N-m (37 ft. lbs.)
2.60 N-m (45 ft. lbs.)
3.70 N-m (52 ft. lbs.)
4.80 N-m (59 ft. lbs.)
5.Loosen bolts 2-3 turns
6.15-25 N-m (11-18 ft. lbs.)
7.Long bolts an additional 85-105° 8.Short bolts an additional 65-85°

13.For each valve, rotate the crankshaft until the tappet rests on the base of the camshaft lobe, install the pushrods and torque rocker arm fulcrum attaching bolts to 5 N-m (43 in.lb). 14.Once all of the rockers are in place and temporarily torqued, torque all fulcrum arm bolts to 25-35 (19-25 ft lbs). For this step the camshaft may be in any position. 15.Torque rocker arm cover bolts to 9-12 N-m (80-106 lbs.in.).
I've come into this world with nothing and still manage to have some of it left.
