Drain block of antifreez to drain heads

I am taking the heads off of my 3.0 and am wondering if there are any drains on the block. From past experience it seems when you pull the heads a bunch of antifreeze gets in the cylinders.

I drained the radiator, then pulled off the lower rad hose and thermostat/housing. Also pulled off the little hose on the right side of the thermostat/water pump that goes to the oil cooler and lowered it to drain the block. I got absolutely no antifreeze in the cylinders when I pulled my heads off.

Good luck getting to those block drain plugs with the engine mounts bolted to the block.
