Not really a hard proceddure. Your biggest challenge will be to reset the timing on the engine, but can be done relatively easily if done right. Simply mark timing belt, Cam gear, and top of block with a permanent marker. Good idea is to rotate engine by using a large socket on the crankshaft until timing marks line up, then mark all items (timing belt, Cam gear, and top of block) First, you've got to remove all the items connected to the head itself, (carb assembly and any other items). A good idea is to take some digital photos of the top, side and all items connected to the head so you can reference when re-assembling later. After removing all components, remove the valve cover. Once removed, you'll have to take out all the head bolts. These will be REALLY tight due to each bolt being torqued. Remove the head, use a large plastic mallet (hammer) and loosen the head by tapping on the sides. Once loose, remove the head and place on a soft surface (several layers of cardboard) Use a putty knife and remove the old head gasket. Scrape any residual oil build up or other material from head and top of engine block. Place new head gasket on the engine block in accordance with service manual or MFG recommendations. Carefully replace head on top of the head gasket and place head bolts into holes you removed them from. Tighted down with regular socket drive until nice and snug. Use torque wrench and tighten bolts using star method as indicated in service manual or ask anyone who's worked on engines to show you. Reset Cam and timing marks with marks you made and replace the timing belt. Use photos you took prior to disassembly to place all items back on the head.

replace head gasket
My 2001 Nissan Sentra GXE has a blown head gasket. My mechanic is quoting me $700 for labor plus parts (total in the $1200 range). Based on his hourly rate of $90 per hour, he must be planning on about 8 hours. Of course that's for an experienced professional. I'm sure if I were to do it myself (assuming I had the ability) it would take much longer.

The gasket for a 1997 pickup was around $40.00-$50.00, if i remember right and that was at NAPA.
You don't have a timing belt, you have a timing chain..(that's for the other foreign automaker...that charge way to much at the lot..but are way too cheap to give you what you pay for.) you timing chain is located under you valve cover gasket, you would have to remove it in order to get at the chain.
To replace the oil pan gasket on the Cavalier you need the tool box to open where it is located. After opening, you can proceed to replace the oil pan gasket.
By removing the oil pan and cleaning the surface and installing a new gasket.

The intake and exhaust manifolds, along with the timing belt will have to be removed to gain access to the head. Remove the head and replace the gasket. Torque the bolts down to the manufacturer specs and in the order Nissan suggests.
the knock sensor is located under the intake manifold, with a flash light you can see it however you have to remove the intake manifold to replace the knock sensor , also you will need to replace the intake gasket set as well!

If you have to ask that question you shouldn't do it yourself as removing a cylinder head is not for the inexperienced. if you do decide to do it yourself make sure you have all the proper tools, and a repair manual, you'll need a full range of metric tools including a torque wrench. follow the manual for the rest of the instructions.
