ahhhh! bleading sucks
this is not what you want to hear but you just need to keep after em! lifting the buggy is a good idea! i do that myself, you can also take the calipers off and point one side of the wilwoods strait up! you will need to put something close to your rotor size between the pads though when you do this another thing has your master been bled? if not raise the front of your buggy and bleed the master because the master feeds from the front(which will be the lowest point if you are bleading from the rear) we have been bleading on racefreaks for 4 days and no matter how many times you do it, it never gets easier 
if you look at the brake forum there is a post on how to make a power bleader on the cheap and i highly advise to give it a try!!! hope that helps
And wear your googles and surgical mask while grinding or welding.You will breath and see clearly the next day.Lowes sells some googles with +150 200 and 250 reading spectacle lens built in. NICE for ol fokes. Oh , and when you high speed grind and you have 10,000 orange sparks hithing your wifes new car. A week later these micro -scopic steel balls that have embedded in the paint start to rust and streak and you've got some splainin dado. One more. If you have to drench a super heated part in old motor oil to 1/2 a$$ harden it. Do it outside. It will set the bucket of oil on fire when it splashes. DON'T splash it on your hands or clothes.The compt says their is a little more to it as far as hot cold hot cold so read up and BE SAFE!Don't burn your house down or yourself! If your sweat shirt catches on fire turn it inside out as you pull it off then smother any thing else with it. Don't set a battery down with the caps off or acid will splash in your eyes. Wash your eyes with ANYTHING RITE NOW!Motor oil, your last beer ,Obama's pi$$,what ever. 
Keep in mind your ft pedal has a small piston and your calipers have 2 Large ones (in your case, 4), so any games played on the rotor means a HUGE volume difference for the ft pedal to make up.
