Block removal
Yep that's what I meant. The freewheel that I had trouble with was a notched one, requiring a removal tool with two pins. [What I meant initially was if you don't have the tool for a notched freewheel, you may be able to remove the small sprockets so the notches are exposed and improvise a tool.] I did managed to get mine off with the tool clamped to the hub with a skewer, but damaged the notches, damaged my tool, stripped the threads off the hub, taught my kids new swear words and learnt some life lessons >.< After the freewheel was off I was determined to service it, so opened the outer cone using a hammer and punch. It was all perfect inside, no need to have opened it. Also to get the pawls and balls back in you need to be an ambidextrous octopus. All in all not my finest hour(s). [It did clean up nicely though, and at least the notches aren't beyond use.]
Wishing @jeff80 the best of luck with his removal!

Block removal
It sounds to me as though there's some confusion here. I think the 'pin holes' referred to are in the outer cone of the freewheel bearing. As Sheldon Brown says, if the notches for the block remover are damaged , the block is knackered and will have to be binned. So, remove that outer cone (n.b. left hand thread - generally stamped 'unscrew' with appropriate arrow) , then throw away the outer part and grip the central core in a bench vice - unscrew as described above.
