Try making a lifter tool out of 1/8" steel rod. Wrap the rod in velcro, running the velcro long ways (you might have to split the velcro strip down the center). Then with the cam all the way in, spin the cam a couple of times in both directions to throw the lifters up and then slide one rod down each of the two holes up and to the side of the cam. That should lock the lifters up and away from the cam. Then when you pull it out, you need to turn it and finesse it out. You need to be careful of the cam bearings and just wiggle until you can ease it past those.
It sounds like you're taking as long to do your cam install is it is to do ours.

We just ran into a bit of a snag between the ASP pulley and the double roller timing chain. Time to pull it off and get it machined down, but we called it a night. Good luck and lemme know if you've got some more questions.
