A pair of snub-nose plyers is what I used. Just get a grip on 'em and wiggle back 'n forth as you pull up. They should come off that way.
Did you reference any cam install guides to see what they recommend?

no...but i've read most of the cam install guides before...when i was thinking of doing my cam swap myself...and don't recall anything about valve seals or seats in any of them.
they were either cam only or swapping heads.
but i'll look around.

Now, if your cam/spring package came with new seats, you're going to need to remove the valve stem oil seals. Using a pair of pliers, grab the oil seal as shown in the picture and wiggle/pull upwards and work the seal off.
If you have a 2001+ car, the oil seals and stock spring seat will be one piece and you just pulled both out. If you have a 2000 or earlier, the oil seal will be a small black or brown thimble shaped thing, and you can now remove the stock spring seat (using a pen magnet is easiest to pick it up).
Now that you've got the old seal and seat removed, place your new seat down until it's flush on the head surface. Now you need to install *new* seals. The seal for the exhaust and the seal for the intake valves are different, so make sure you know what valve you are working on (if the valve lines up with a port on your exhaust manifold/header, then it's an exhaust valve, otherwise it's an intake valve). The seal for the intake is black, and the seal for the exhaust is brown.
Before you install the seal, smear some motor oil onto the valve stem and onto the black valve guide. Place the seal onto the top of the valve guide, take a deep 12 point 10mm or 12mm socket and put it over the valve so that it's up against the valve seal, and tap it with a hammer until it seats solidly. There will be a gap between the seal and the seat, that is okay!
