The tapped holes for the head studs often strip out of the case; the 
lowers suffer from this more often than the uppers.  If they will 
take torque, though, that may not be your problem.

Loose head studs will affect valve clearances, too.

It's too late to do a compression test, you need the starter to do 
that, so the engine at least needs to be attached to the 
transmission, and the test is best done warm.

It is held in place with two dowel pins one in the big cast lug in 
each "armpit."  They are easy to part if you use a cold chisel in the 
parting line.  Work carefully, side to side, and you will inflict 
minimal damage.

Use a puller that threads (M8 x 1.25) into the fan hub to pull it off 
the end of the crank.  DO NOT be tempted to pry it off.  It may come, 
but only after it bends.
