Hi there,

The operation of replacing valves is a precise machining operation which you will not be able to do, as for removing the head or heads, this you may be able to do if you are competent with working on engines, I would suggest that you get a work shop manual and read that section and decide if you have the tooling and are confident to do this job.

Require a degree of know how and special tools Steps needed to remove the heads

3.2L & 3.5L V6 -2000 Chrysler 300M

Removal
1. Release fuel pressure. Disconnect negative battery cable from remote jumper terminal located at right strut tower. Drain cooling system. Cover drive belts and/or pulleys to prevent contact with coolant. If coolant contacts belts and/or pulleys, flush both with clean water.
2. Open radiator drain located at lower right side of radiator. DO NOT use pliers to open radiator drain. Remove coolant recovery reservoir cap, and open air bleed valve located on water outlet connector at front of engine.

3. Remove upper radiator crossmember. Disconnect fan assembly connector. Remove fan assembly. Remove drive belts. Using Crankshaft Pulley Holder (8191), hold crankshaft pulley and remove center bolt.
Using a 3-jaw puller, remove crankshaft pulley.

4. Remove timing belt covers. Remove camshaft sprockets. Remove intake manifold assembly. See INTAKE MANIFOLD BELOW. Remove cylinder head covers. See CYLINDER HEAD COVERS BELOW. Remove rear timing belt covers and water pump. Remove water pump "O" rings. Remove cylinder head bolts, and remove cylinder head.

INTAKE MANIFOLD

Removal (Upper)
1. Disconnect negative battery cable from remote jumper terminal located at right strut tower. Remove front engine compartment supports and upper radiator crossmember. On all models, remove air inlet resonator and tube. Remove throttle and speed control cables from throttle arm and bracket.

2. Disconnect Idle Air Control (IAC) motor, Intake Air Temperature (IAT), Manifold Absolute Pressure (MAP) sensor, Throttle Position Sensor (TPS) and Manifold Tuning Valve (MTV) connector, if equipped. Disconnect vapor hose, brake booster hose, speed control reservoir and Positive Crankcase Ventilation (PCV) hose.

3. Remove right and left upper intake manifold supports. Remove support brackets at intake manifold front corners and MTV. Loosen upper fastener attaching throttle body to support bracket. Remove clips attaching EGR tubes to intake manifold. Remove upper intake manifold bolts and manifold.

Removal (Lower)
1. Release fuel pressure. Drain cooling system. Cover drive belts and/or pulleys to prevent contact with coolant. If coolant contacts belts and/or pulleys, flush both with clean water. Open radiator drain located at lower right side of radiator.

2. DO NOT use pliers to open radiator drain. Remove coolant recovery reservoir cap, and open air bleed valve located on water outlet connector at front of engine. Remove cylinder block drain plugs located below each exhaust manifold.

3. Remove upper intake manifold. Disconnect fuel injector and coolant temperature sensor connectors. Disconnect heater hose quick connect "T" from heater tube located at rear of manifold. Disconnect Fuel supply hose from fuel rail.

4. Remove throttle body bracket-to-fuel rail bracket screw. Remove fuel rail bolts. Remove fuel rail and injectors as an assembly. Remove lower intake manifold bolts and manifold.

After heads removal need to be machined
