Living in the rust belt makes for some nasty ones.
I prefer to drill off center so the bolt ends up C or crescent moon
shaped so it releases on one edge and can spin out.
Gotta drill it either way anyway.

Sometimes if you fear the bolts are going to be a pill you should try
to break them loose right after engine is shut off hot. Yes you do
need some protection (like some leather work gloves and a long sleeve
shirt) but when block is hot the bolts will come out easier due to
cast iron expading more than steel.
