Default Torque for prop bolts

Quick question for the group. When setting the torque on prop bolts (I
have bolts with nuts), if the hole for the cotter pin doesn't line up
with the castleated nut at the proper torque setting, is it better to go
tighter or looser to get the hole lined up. My gut instinct says
tighter, but....

Use a pair of Belleville washers rated for about 2000 lb under each
bolt head, installed with their conacave sides facing each other. See
if you can get to the recently-deceased Vance Jaqua's web site, and see
his write-up on the Belleville use.
