Good Morning. Here is step by step along with a photo. I hope this helps! Best of Luck.

1. Install the valve covers and tighten the bolts in sequence to 43 inch lbs. (5 Nm).
2. Install the valve covers.
3. Install the ignition coils.
4. Install the cables from the spark plugs.
5. Install the intake manifold.
6. Install the vacuum hose, fuel hose and coolant hose.
7. Install the breather hose and air-intake hose.
8. Connect the upper radiator hose.
9. Connect the negative battery cable.
10. Fill the cooling system.

Lower Intake:

1. Use a skin coat of RTV silicone on both sides of the water passage ports (outer most holes) and put the new lower intake gaskets into place
2. Hand tighten the 13mm head intake bolts and Torque the bolts , starting from the center and working your way out in a circular pattern
3. Torque these bolts in a few small increments until they have reached 250 inch pounds of torque.
4. Upper Intake Plenum:
5. When installing the intake air plenum , be sure to catch the four center bolts and the two side bolts (stiffener brackets) before tightening , The center bolts should be torqued to 250 inch pounds .The fuel rail bolts should be torqued to 100 inch pounds

Install the cylinder heads. Use new gaskets and tighten the bolts, in sequence, as follows:

1. Step 1: Bolts 1-8 to 20 ft. lbs. (27 Nm)
2. Step 2: Bolts 1-10 verify torque without loosening
3. Step 3: Bolts 9-12 to 10 ft. lbs. (14 Nm)
4. Step 4: Bolts 1-8 plus 1 / 4 (90 degree) turn
5. Step 5: Bolts 9-12 to 19 ft. lbs. (26 Nm)

Install the cylinder head bolts. Starting at top center, tighten all cylinder head bolts in sequence as shown in illustration, using the Cylinder Head Bolt Wrench (09221 - 32001) or equivalent. Repeat the procedure, re-tightening all cylinder head bolt to the specified torque. (torque spec is Cold Engine 105-115 Nm (76-83 ft lb) )
. Install the timing belt tensioner pulley.
. Install the timing belt on the camshaft sprocket, making sure that the tension side is tightened by turning the camshaft sprocket in reverse, all timing marks are in alignment.
. Adjust the timing according to "Timing Belt"
. Install the rocker cover and tighten the bolts to the specified torque. Tightening torque: Rocker cover belt:

2.5-3.5 Nm (25-35 kg.cm, 2-3 ft. lbs.)

. Install the timing belt cover.
Install the new intake manifold gasket and the intake manifold. Tighten the nuts and bolts to the specified torque.
Install the new exhaust manifold gasket and the exhaust manifold. Tighten the exhaust manifold attaching nuts to the specified torque.
. Install the surge tank and tighten the nuts bolts to the specified torque.
. Install the power steering oil pump and bracket.
. Install the ignition coil.
. Install the air intake hose.
Connect the vacuum hose, fuel hose and water hose.
. Install breather hose.

Lower ball joints. Tighten the pinch bolts to 69-85 ft. lbs. (93-115 Nm). Outer tie rod ends. Tighten the nuts to 43-58 ft. lbs. (59-78 Nm). Sway bar links. Tighten nuts to 69-85 ft. lbs. (93-115 Nm). Hub retaining nuts. Tighten the hub nuts to 177-199 ft. lbs. (240-270 Nm). Front wheels. Tighten the lug nuts to 65-79 ft. lbs. (88-108 Nm).

Depends on how MECHANICALLY INCLINED you are. Have you done any repair work on vehicle engines before? It's not that difficult to do if you know how to turn a wrench/ratchet and THINK about what you are doing and what you are dealing with... .attention to details. Ya think? On the 04 2.7 lit V6 Sonata, there are two nuts and 5 bolts (two long and three short) which hold the plenum to the RISER manifold. There are an additional 3 to 4 bolts at the rear (firewall side) which support the plenum (they're all 12mm bolts). You'll need to remove the intake air hose to lift the plenum out of the way to access the 3 plugs on the RH side (rear) of the engine. You'll want to replace the plenum gasket when you do this. When you reinstall the plenum, the tightening torque is 11-14 lb.ft. Do not tighten the REAR support bolts until after you torque the surge tank bolts to the intake (riser) manifold.
