INSTALLATION - RIGHT CYLINDER HEAD
NOTE: The cylinder head bolts are tightened using
a torque plus angle procedure. The bolts must be
examined BEFORE reuse. If the threads are
necked down (2) the bolts should be replaced.

edge against the threads. If all the threads do not con-
tactthescale(2),theboltshouldbereplaced.

CAUTION: When cleaning cylinder head and cylin-
der block surfaces, DO NOT use a metal scraper
because the surfaces could be cut or ground. Use
only a wooden or plastic scraper (1).
1. Clean the cylinder head and cylinder block mating
surfaces.
2. Position the new cylinder head gasket on the locat-
ing dowels.
CAUTION: When installing cylinder head, use care
not damage the tensioner arm or the guide arm.
3. Position the cylinder head onto the cylinder block.
Make sure the cylinder head seats fully over the
locating dowels.
NOTE: The four smaller cylinder head mounting
bolts require sealant to be added to them before
installing. Failure to do so may cause leaks.
4. Lubricate the cylinder head bolt threads with clean
engine oil and install the ten M10 bolts.
5. Coat the four M8 cylinder head bolts withMopar
Lock and Seal Adhesivethen install the bolts.
NOTE: The cylinder head bolts are tightened using an angle torque procedure, however, the bolts are not a
torque-to-yield design.
6. Tighten the bolts in sequence using the following steps and torque values:
Step 1: Tighten bolts 1–10, 20 Nꞏm (15 ft. lbs.).
Step 2: Tighten bolts 1–10, 47 Nꞏm (35 ft. lbs.). Tighten bolts 11–14, 25 Nꞏm(18 ft. lbs.).

CAMSHAFT - LEFT
DESCRIPTION
The camshafts consist of powdered metal steel lobes which are sinter-bonded to a steel tube. A steel post or nose
piece is friction-welded to the steel camshaft tube. Five bearing journals are machined into the camshaft, four on the
steel tube and one on the steel nose piece. Camshaft end play is controlled by two thrust walls that border the nose
piece journal. Engine oil enters the hollow camshafts at the third journaland lubricates every intake lobe rocker
throughadrilledpassageintheintakelobe.
REMOVAL
1. Remove cylinder head cover (1) (Refer to 9 -
ENGINE/CYLINDER HEAD/CYLINDER HEAD
COVER(S) - REMOVAL).
CAUTION: When the timing chain is removed and the cylinder heads are still installed, DO NOT forcefully
rotate the camshafts or crankshaft independently of each other. Severe valve and/or piston damage can
occur.
CAUTION: When removing the cam sprocket, timing chains or camshaft, Failure to use Special Tool 8350
will result in hydraulic tensioner ratchet over extension, requiring timing chain cover removal to reset the
tensioner ratchet.
2. Set engine to TDC cylinder #1, camshaft sprocket V8 marks at the 12 o’clock position.
3. Mark one link on the secondary timing chain on both sides of the V8 mark on the camshaft sprocket to aid in
installation.

8. Starting at the outside working inward, loosen the
camshaft bearing cap retaining bolts 1/2 turn at a
time. Repeat until all load is off the bearing caps.
CAUTION: DO NOT STAMP OR STRIKE THE CAM-
SHAFT BEARING CAPS. SEVERE DAMAGE WILL
OCCUR TO THE BEARING CAPS.
NOTE: When the camshaft is removed the rocker
arms may slide downward, mark the rocker arms
before removing camshaft.
9. Remove the camshaft bearing caps and the
camshaft.
INSTALLATION
1. Lubricate camshaft journals with clean engine oil.
NOTE: Position the left side camshaft so that the
camshaft sprocket dowel is near the 1 o’clock
position, This will place the camshaft at the neu-
tral position easing the installation of the camshaft
bearing caps.
2. Position the camshaft into the cylinder head.
3. Install the camshaft bearing caps, hand tighten the
retaining bolts.
4. Working in
1⁄2turn increments, tighten the bearing
cap retaining bolts starting with the middle cap
working outward.
5. Torque the camshaft bearing cap retaining bolts to
11 N ꞏm ( 1 0 0 i n . l b s . ) .

VALVES & SEATS - INTAKE/EXHAUST
DESCRIPTION
The valves are made of heat resistant steel and have chrome plated stems to prevent scuffing. Each valve is actu-
ated by a roller rocker arm which pivots on a stationary lash adjuster. All valves use three bead lock keepers to
retain the springs and promote valve rotation.
REMOVAL
NOTE: The cylinder heads must be removed in
order to perform this procedure.
1. Remove rocker arms and lash adjusters (Refer to 9
- ENGINE/CYLINDER HEAD/ROCKER ARM /
ADJUSTER ASSY - REMOVAL).
2. Remove the camshaft bearing caps and the cam-
shaft.
NOTE: All valve springs and valves are removed in
the same manner; this procedure only covers one
valve and valve spring.
3. Using Special Tool C-3422–B or C-3422–C Valve
Spring Compressor and Special tool 8519 Adapter,
compress the valve spring.
NOTE: It may be necessary to tap the top of the
valve spring to loosen the spring retainers locks
enough to be removed.
4. Remove the two spring retainer lock halves.
NOTE: the valve spring is under tension use care when releasing the valve spring compressor.
5. Remove the valve spring compressor.
6. Remove the spring retainer, and the spring.
NOTE: Check for sharp edges on the keeper grooves. Remove any burrs from thevalvestembeforeremov-
ing the valve from the cylinder head.
7. Remove the valve from the cylinder head.
NOTE: The valve stem seals are common between intake and exhaust.
8. Remove the valve stem seal. Mark the valve for proper installation.
