What makes them nearly as easy as the previous Golf 1>3 is that the AKL head is pretty simple to remove, unlike the head on a 1.8T GTI Golf 4 and the sump is easy to remove on all of them, as long as you don't strip the two M6 threads in the crank oil seal holder.
The way I suggest you start this process is to give new rings the best possible chance of bedding in by flushing the engine out with Millers CRO before you even start, this can be bought from the forum Sponsor Opie Oils. With the pistons out, it would be a good idea to give the bores a very quick light honing
http://www.lasertools.co.uk/item.aspx?cat=1090&item=640 . The action you use for this is quite important so ask when you get that far. You must remove the piston oil spray jets to do this or you will smash the stones.
If you found a bore to be damaged or a liner cracked, pulling the block and re-boring it simply is uneconomic and a cracked liner means the block is FUBAR, even re-ringing is uneconomic to pay a pro to do it, DIY is fine though.

This list only accounts for the absolute minimum required to do the job correctly and doesn’t take account of the inevitable extras required when doing something on an old car. The brands are the ones I would use. This would take care of any possible wear related head or ring oil use issues. You may find with the valves out that the exhaust valve guides need replacing, these are only £4 each from Febi but have to be professionally fitted. It is extremely unlikely that the piston gudgeon pin bushes will be worn so even if you fitted new pistons they should still be OK. You should be able to polish up and lap the valves even if it needs new guides, the valves MUST not be re-worked, only hand lapped, but exhaust valves are only £15 each from Febi and the inlet valves never wear. You need to add to this the cost of having the head very lightly refaced, just a tickle-no more. If you are interested, I can do some very cometetive prices on many of those parts, especially Febi.
