The animal tissue processing manual is intended to be guidelines although
one can certainly try the protocols as written.  You may have to see what
is in the manual, then tweak the protocol for larger tissue.  

You did not give your protocol for guinea pig brains - it would help plus
the dimensions on the brain.  Larger size tissues will need longer
processing times.
