I always just used the balancer bolt... i guess I'm doing it wrong!

you do not want to strip the threads in the crank or break the head of the bolt off.....you have been lucky so far....

but If for whatever reason you have to use the bolt, remove all the plugs and your safest bet is to turn it using a clicker torque wrench set to 65 ft/lbs

I have used that Proform tool on many big and small blocks with multiple styles of balancers and never had a fitment issue.
As far as balancer bolts I use ARP hex head style with a 1/2" square drive in the middle so I can rotate the engine once it is assembled with pulleys and installed in the car using clockwise rotation and no spark plugs.
