Too much engine work at once

So since my engine is pretty much apart, but still installed, heads off getting redone, etc. I am on the fence about doing a new cam at the same time. My questions is am I doing too much stuff at once? Or shouldn't do something at the same time as the others. I won't have it all back together for about 4 weeks for the "planned" items, waiting on headers.

Items that are planned:
Doing valve job, therefore new head gasket etc that go along with that.
Radiator rodded and refinished.
Doing headers and 2.5 exhaust.
Have a leaky oil pan so I am doing pan gasket and since that will be off...
I am doing new HV oil Pump. While that is off...
I am doing Rear Main seal...

Items I am thinking about doing:
With the pan off I am on the fence with doing timing set...
And then I might as well do a new Voodoo 701 cam.

So too much? Block and pistons look good. 105k on the engine.

Thanks for the help
