I'm not an expert, you can sometimes see tell tale signs of how an engine ran, good or if it had issues, by the type of discoloration of the top of the valves. Notice one the difference in color? When you take a valve out, you're able to see the seat. Check for damage, excessive wear etc... if you have damage, or wear - they'll need redone. Before taking the springs off, you can check to see if all valves are sitting even with one another by placing a straight edge (straight piece of metal, long enough to ride the length of the head) along the valve ends. If you notice some that are excessive in not being even with the rest, extra work may need done. Your machines will know what all to look for, just giving you something to do.

Yes, the crank can be reused if in good shape (I reused mine) - but only if it'll match whatever build you are after. I don't think we punched our parts, just used a marker - place them in a box in order. You're machinist should know to keep the order when done.
