It's not really difficult I would say a 4?
CYLINDER HEAD
CAUTION:To prevent cylinder head damage, wait until coolant temperature is below 100 °F (38 °C) before removing cylinder head.
Removal
Disconnect negative battery cable. Drain cooling system. Disconnect power brake unit vacuum hose. Disconnect engine ground strap from cylinder head and transaxle housing. Remove air cleaner cover. Place No. 1 cylinder at TDC of compression stroke.
Disconnect condenser, ignition coil wire, and ignition coil primary wiring. Place shop towel on top of fuel filter and relieve fuel injection system pressure by slowly loosening fuel injection service bolt. See Fig. 1. Disconnect throttle cable from throttle body.
Disconnect fuel vapor canister vacuum hose (at throttle body). Disconnect engine harness from cylinder head and intake manifold. Disconnect oxygen sensor wire.
Disconnect radiator and heater hoses from cylinder head. Remove hose between thermostat housing and intake manifold. Disconnect exhaust pipe from exhaust manifold. Disconnect pipe and coolant by-pass outlet hose.
Disconnect spark plug wires and remove distributor assembly. Remove intake manifold, wire harness, and alternator pulley covers. Remove alternator and belt.
Remove power steering pump. On models with A/C, disconnect idle control solenoid hoses. Disconnect cruise control actuator (if equipped). On all models, disconnect exhaust pipe from manifolds. Remove air cleaner base mount bolts.
Disconnect hose between intake manifold and breather chamber. Remove air cleaner base. Remove EGR tube from cylinder head. Remove exhaust manifold cover nuts. Remove air suction tube nuts from exhaust manifold and air suction valve.
Remove intake manifold assembly from cylinder head. Remove thermostat housing/coolant manifold assembly from rear of cylinder heads. Remove timing belt upper covers.
Turn crankshaft clockwise to bring piston in cylinder No. 1 to TDC of compression stroke. Advance crankshaft an additional 15 degrees from TDC position. Loosen timing belt tensioner adjustment bolt. Slip timing belt off camshaft pulleys.
CAUTION:Advance crankshaft 15 degrees from TDC (as specified) before removing timing belt. This will prevent valves from coming into contact with pistons.
Remove front camshaft pulley. Prior to removing rear camshaft pulley, adjust camshaft position so that no valve is fully open. Remove top 2 bolts first and then remaining bolt. Remove rear camshaft pulley.
Remove upper cover back plates. Remove valve covers. Remove cylinder head side covers. Remove bearing cap pipes and camshaft journal bearing caps. Remove camshafts.
Remove rocker arms and push rods. Mark parts for installation reference. Loosen cylinder head bolts a few turns at a time in reverse order of tightening sequence. See Fig. 6. Remove cylinder head from vehicle.
