Remove Valve Covers (ECH EFI)
1. Remove screws securing each valve cover. Note
valve cover differences for proper location in
reassembly. Ensure any brackets removed are
reassembled in same location.
2. Covers should lift off without prying.
Remove Spark Plugs
Remove spark plug from each cylinder head.
Remove Cylinder Heads and Hydraulic Lifters
NOTE: Cylinder heads are retained using either screws
or nuts and washers on studs. Do not
interchange or mix components.
1. Remove screws or nuts and washers securing each
cylinder head. Discard screws or nuts and washers
once removed. Do not reuse. Studs (if present)
should only be removed if damaged or if cylinder
reconditioning is necessary. Once removed, they
must be replaced.
2. Mark location of push rods as either intake or
exhaust and cylinder 1 or 2. Push rods should
always be reinstalled in same positions.
3. Carefully remove push rods, cylinder heads, and
head gaskets.
4. Remove lifters from lifter bores. Use a hydraulic lifter
tool. Do not use a magnet to remove lifters. Mark
lifters by location, as either intake or exhaust, and
cylinder 1 or 2. Hydraulic lifters should always be
reinstalled in same position.
