The best way to do this is to remove the engine from the car. Then mount it on an engine stand if you can as it will make things a whole lot easier.
Next, remove the rocker cover & carefully remove the whole rocker assembly, then remove the push rods. Keep them in order so that they go back into the same place if possible. Loosen the altenator & remove the fan belt. Remove the fan from the water pump too. Remove the oil pump & the distributor. Remove the spark plugs too. Drain the oil, all of it.
Rotate the engine untill it is upside down & remove the oil pan. Remove the crank pulley, then remove the timing case. Remove the timing chain tensioner, then the cam sprocket retaining bolt. Remove the cam sprocket & chain. Remove the cam retainer & carefully, very bloody carefully, remove the cam. Support it at the rear so as to avoid damaging the cam bearings in the block. Remove the tappets & check them for correct radius of their face. Either have them radius ground, or replace them with new. If reusing them, try to put them back in the same hole if possible
Heavily lube the new cam with a suitable cam break in lube, & insert it with even more care than the one you took out. Re-assembly is basicly the reverse of the removal, but you will need new gaskets, & i sugest that a new timing case oil seal would be a good idea. Examine the sprockets closely, particularly the crankshaft one as it turns twice for every once of the cam one. There are fewer teeth in contact with the chain too, so this one wears more than the cam sprocket. If it is at all suspect, then replace the sprocket[s] & chain with new. Check the wear pad on the tensioner. If it is more than half worn, then think about a new one of these too.
Complete the re-assembly & adjust the tappets, & set the timing as per the book. Hows the clutch? If it is old, then take it off & have a look at it. Renew if necessary. You would be pizzed if the old cluch started to slip with the new power of the engine. Re-install the engine.
When you start it, run the revs straight up to the speed that is recomended by the cam grinder for the time that is recomended. This is a critical break-in time for the cam. Give the engine a complete tune up when it is hot & after the initial break in period
After the recomended interval, change the oil & filter, then enjoy the fruits of an afternoons work. Like Freak said, it just slips in once the front cover & gear[?] are off. Happy motoring.
