Pulling heads

Make absolutely certain you brake cleaner (preferably non-chlorinated) the head bolt holes then use compressed air with a small hose or long nozzle to blow all liquid out of the bottoms. If you happen to screw a bolt down on top of liquid, you'll probably shatter the block.

No, they are not considered reusable since they have one-time-crush sections that allow them to seal perfectly when the head is torqued down. I wouldn't even use one that was dropped on the ground or had the box crushed.
