Looks like a good plan if Vernon doesn't come through. I think you could do it if you take your time, follow the Haynes manual, have your wife and others around to assist, and have the basic wrenches and sockets available. The only special tool needed is a torque wrench.
While you sort things out, install the 20 or so exhaust and intake manifold studs in the new head. Use the two nut method shown in this U-tube:

Install the shorter threaded end into the head and torque the studs to 15 ft/lbs. It's easier when the head is off and will save you or Vernon shop time. If the new head didn't come with studs for the fuel pump, use ones intended for the exhaust manifold. Then they'll be in place if you choose to bolt the intake manifold to the head and install them together on the block. Later, just remove a couple studs from the old head to use as the "missing" exhaust studs.
Lastly, remove a cam tower/cap bolt and shoot a blast of canned air at the bottom of the bolt hole to clean out any metal shavings lurking in the hole. Then reinstall the bolt. Do one bolt hole at a time and you won't have to worry about the hydraulic adjusters falling out of the rockers. Save that for when you decide which cam to use.
