Apply OE/HDO to exhaust valve (18) and install valve (18) in valve guide (15) from which it was removed. NOTE l Valve caps on exhaust valves are rotaters. l Perform step 2 for 6.5L engines and 1990 and above 6.2L  engines.  Perform  step  3  for  previous  model  6.2L engines. Install seal (21), valve spring shim (14), valve spring (13), valve stem seal (12), shield (11), and valve cap  (9)  on  exhaust  valve  (18). Install valve spring shim (14), valve spring (13), shield (11), and valve cap (9) on exhaust valve (12). Using spring compressor, compress valve spring (13) and install valve seal (10) in groove (17) in exhaust valve (18) and install valve keys (8). Slowly release spring compressor.
