Thanks Z06 Addict.
I knew where the radiator drain is but to do a good job of draining & flushing the system when changing the coolant you need to drain both sides of the block. Otherwise you leave most of the coolant in the block if you just drain the radiator.
It looks to me like the block drain plugs (if they are there) are going to be a real bear to get to.
Is there a doctor in the house?
