when doing an engine rebuilt or any kind of work that involves lots of little bits, clear your workbench and lay them out on a piece of brown cardboard. Using a black marker number them 1 to however many you have then you'll know which order they came off, to go back on.
A bit anal i know but some stuff i do can be tricky.

If you have an awkward bolt head that refuses to come out cos its rounded, get a socket thats smaller than the bolt head ie 16mm use 15mm, heat up the socket if you can, and tap it with a copper mallet on to the bolt. Heat will expand it then it cools, clamping the socket. Use plenty of release spray and twist slowly.
This works well in Spline headed bolts and Torx headed bolts.

if you have a spring under serious tension and you want to remove it, get a piece of braizing wire, make a triangle "handle" at one end, then make a hook at the other. Loop the hook around the spring end you want to remove and pull.
I found Piano wire works best but any wire will do.

Regrinding Valves?? dont buy expensive gringing paste..make your own!!
Any household soap powder (i found Non Bio is best) and a mild green liquid soap that feels soft as your face (no names dropped there) mix it up and away you grind. It slides better than the paste, easier to clean off and if you have some spare, wash the grease off your hands with it.
Dont forget to moisturise you hands after as the soap powder strips your hands of it natural oils.
