Taking it apart is easy, putting it back together correctly is more difficult. I recommend buying the head gasket set and head bolts at the dealership. Find out what all is included in the head set..ie:head bolts, valve cover gaskets, egr gaskets, thermostat gasket-etc. Replace the spark plugs and thermostat at the same time and make sure to flush the coolant and change the oil after the repair. I recommend changing oil twice. Follow the correct tightening sequence and torque specifications and you must use new head bolts. Have a reputable machine shop pressure check and resurface the heads for you. Good Luck.

If you have a digital camera, or can borrow one, take a picture of the engine before you begin. It will help you later to put the hoses and electrical lines back where they were. Next, be clean! Not you personally, the engine compartment. If there's dirt, leaves, crud, or any debris in the area, remove it before you start. Get some masking tape and tag all the wires and hoses. Whatever system you use is fine as ling as you know where they go. Take pictures as you go for later reference if needed. Get all the hoses and brackets off the head first. Remove the valve covers only when the engine surfaces are clear of debris. Remove the rockerarm shaft noting its orientation. Remove the cylinder head bolts one at a time and mark the location for re-insertion. Remove the valve pushrods. Carefully note the location of each valve pushrod. Lift the cylinder head very carefully and be sure not to damage the Intake manifold gasket and sealing edge. The cylinder head can be heavy and care must be taken to avoid banging it on its sealing surfaces. Once it is off and secure, the top of the engine block must be cleaned of all gasket residue. Be sure you don't get any debris into the cylinders! Inspect the cylinder head for worn or burned valves. If all is well, reverse the procedure. The head should be clean and shiny when you put it back on. No loose crud flakes. Be careful of the instructions in the gasket kit! The gaskets fit only one way and can be wrecked if you do it upside down. Your %26quot;top end%26quot; kit should have a head gasket and an intake manifold gasket. Refer to manufacturers specs and torque everything properly. Good luck! Actually it's fun if you've got the attitude for it.
get a Chilton,s or a motor,s manual....take pictures or make note,s to aid in reassembly....buy the best gasket set available....replace head bolt,s.....do all cylinder head,s not just one...have your head,s checked out at a reputable machine shop...clean all mating surface,s....torque head bolt,s in sequence...drain coolant before starting....refill coolant when finished....change oil when finished....pay attention to detail,it will save you some headache,s...do a complete tune up when finished.........good luck!
