I've been waiting for this message to be answered by someone with more 
experience replacing bulkheads than I have.  Since the chainplates are 
dependent on the bulkhead, I would be inclined to replace it completely. 
  The rot here is most likely due to water infiltrating where the 
chainplates pierce the deck.  It's very important to keep these caulked. 
  Pulling out a chainplate and losing the mast could ruin your whole day.

Since I've not replaced a bulkhead, I'm at a loss as to what advice to 
give there.  I would suggest upgrading the bolts to 5/16" at the same 
time, if you've not already done so.  These bolts should also not be 
fully threaded.  The original fully-threaded 1/4" bolts are the weak 
spot in the rigging design.  Most problems have come from either these 
bolts failing, or the bulkhead/knees failing from rot.
