OK, S3 head removal.... not a hard thing to do in honesty.
Procedure is pretty much obvious to be honest - if it's not then maybe doing it yourself isn't for you...
Anyway - invest in a pukka VAG headbolt tool. Makes the job 100 times easier.
The only other useful tip is with regard to the turbo to manifold bolts. Don't use an E11 socket, they are pants and a crap fit. Use an 11mm multispline socket. Best fit by far...
Thats all I can think of which will help out. The rest is just taking stuff off...
