Blown head gasket

Subject: Blown head gasket


About two years ago I had some head work done on my BN-1.  I replaced the
head using a new gasket. I coated the gasket on both sides with silver spray
paint before installation. This fall the gasket blew between the rear two
cylinders. Does anyone know what might have caused this?  I can't remember
if I re-torqued the head or not...probably not!  
 
I'd appreciate any advice as to what I should do to keep this from
reoccurring.
 
Thanks,
