The easy way:
Have a compressor (say 120psi) handy.
Remove all the rockers from the motor
Get a compression tester, that has a schrader valve that can come out, take it out. This makes the tube wide open.
Put the adapter and tube into the cylinder you want to start on (all plugs removed) and attached your air hose from compressor to the compression tester tube.
This is now pressurizing the cylinder to hold up the valves.
Use your valve spring compressor to compres the spring and remove the valve locks.
Take your spring/retainer off the head
Change the valve seal
Put new spring with new retainer onto head (assumed they are compressed) and put the valve locks back in.
Release pressure on the spring.
Tada
Ready to install springs
Tools for the process, less the compression tester hose (that's likely in the motor)
Hose in a cylinder and spring being compressed with hand crank took
Grabbing valve locks with magnet
Spring off, new seal in place
New spring in place with retainer, just needs locks put back in
That's about it for what I have.
