head will need taking off

Its possible to do it with the head on, but difficult. You need a tool to stop the valves dropping.

Can be done with compressed air.

Get one of these

Screw it into your sparkplug hole on the pot your working on.Get the piston to tdc and apply 80-90psi of air.This will pressurize the cylinder and hold your valve in place.

Don't the valves rest on the top of the pistons if they at TDC?

Yes but it is usually too far of a drop to be able to lift the valve up enough to get the collets on.
