While I was taking a break and staring at it all I came up with two ideas:

1 - if you just need a little more room on the intake side I don't see why you can't just pop all the idler arms off and just remove the bearing caps that hold the eccentric shaft and remove that whole piece.

2 - use the spring compression tool to press all of the valves down slightly one by one with each corresponding cylinder at TDC and remove all of the rocker arms. At this point the valves are all closed on all cylinders and there is no need to rotate the engine. That means you can remove and install the intake cam without having to time it.
