I will heed the advice about just doing the opti for now. It's just such a big job I'd like to get more payback for my time investment.
The opti is not a big job. I've done it multiple times on my wagon and can start-to-finish it in under 2 hours. I have a ram-air intake, so I have less intake crap to move out of the way, though. I'd figure that a fairly competent tech oughta be able to do it in about 4 hours if he's got all of the tools handy.
To do the cam, you have to remove the thing on the end of the crankshaft (requires a special puller) to remove the timing cover, and on top of the motor, you've got to remove the intake (and everything around it) and the lifters. I haven't actually done the cam (but I have replaced the lifters), and doing a cam swap is HUGELY a bigger project than the opti.
