Anyone know if the drain holes in the block are petcocks (sp?) (like a radiator type) or more like a bolt that you need a socket or wrench to open?

They are like brass wing nuts - similar to a radiator petcock but not.
I found that a 1 inch socket (or there-abouts) and ratchet will slip over the "wings" and make removal easy.
PS - its Mark IV, not Gen IV. Gen started with the V - go figure

I generally use a small adjustable wrench on them. Be sure to save them. Those are the good petcocks and they are getting hard to find.

Petcocks in center of block jacets between3 and 5 and 2 and 4 cyclinders left and right one above oil cooler left side other 12 inches back of fuel filter and pump . Make sure put wrench on brass sleeve and also one on plug. Best to back petcock all the way out or sand rust gets in threads and next year they will be a bear to remove.
