<VV> Brake drum seized onto shoes

[Kinzelman, Andy]

Guys,
I am helping a friend with a car that hasn't moved in 20 years.  We are assuming the drums will be stuck onto the shoes.
I believe I saw a tip once about removing the heads from the brake hold down pins to allow the drums to be pulled off.  I don't recall whether the pins were punched through, drilled out, or ground off.  Anybody have any recommendations?
Thanks,
Andy K.
