I've removed my cylinder head, while trying to access another part of my bike, and I was overwhelmed by the carbon build-up around the valves, and piston tops.

I'd really like to remove the valves and go-to-town on all that nasty carbon, but I can't figure out what tools I would need to be able to get at the springs so I can remove the valves.

The Hayne's manual isn't very specific about what kind of valve spring compressor I need, but looking at how little space there is around the springs, I'm thinking I'm going to need a specific kind of compressor.

Any advice would be appreciated here, thanks.
