Can this type of valve seal be installed with the valves held in there closed position with air pressure? Is there a special tool for this?

My guides are .500 with 11/32 stems.

Yep. The fittings are available at most auto parts places. The napa near me stocks them.

Why teflon?

Are you going with a positive seal due to oil use?

Air pressure will hold the valves real well. Even with a 1.44" exhaust and 80 psi there will be well over 100 lbs pushing on the valve. exactly how much depends on the actual diameter at the seat.

You need a sleeve over the stem to protect the seal. You can make one with shrink tubing. The other tool is just bar stock with a hole in it to push the seal on.

I thought the valve guides had to be machined so that a positive seal will lock on the guide? When I changed my valve stem seals, I used some (new) vacuum tubing stuffed into the cylinder, than rotated the crank toward tdc to lock the valves in place.
