My 33-2 does that if I crank things too tight.   (mast step has been rebuilt), 
and I do not have a hydraulic backstay.  It binds at the top of the doorframe.

There are there are j hooks that are bolted through the mast that grab the cast 
mast partners/ collar to which the halyard turning blocks are mounted.  I 
believe these hooks are there keep the mast collar from being lifted by  pull 
of the halyards.    There are shims between the base of the mast and the step 
that can slightly vary height of the mast and therefore the distance between 
the hooks and the step.   Soooo, without those shims, the mast is inclined to 
press the cabin top down, and therefore the top of the head door frame.   If 
shimmed correctly, the hooks don't pull the cabin down, but they keep the deck 
from lifting via halyard pressure etc..
If you have a similar arrangement, this could be impacting things.  

Dave.  33-2
