If your engine has mechanical valve lash adjustment (shim discs on top of solid lifters), don't forget about getting hands on the tools and parts for that as well.
The lash clearance should best be checked on a stone cold engine AFTER the head has been bolted on and torqued so as to put the head in its final installed position and stresses. Seems like when we try to adjust valves with the head on the bench prior to install, you always have to go back and do it again after torquing the head down since things shift around a little bit inevitably.
