On my stupid wagon i've beheaded it several times, each time managing to spill a bunch in the cylinders and down the pipes. I must have got a lot in the mufflers last time as it billowed white smoke for a long time. The antifreeze doesn't just evaporate like water. It took a half hour of embarrassing driving!
You can siphon it out after the intake is off by using a small clear tube down the rear head crossover passage and down through the head gasket hole in the deck.
