Lisle valve spring compressor, junk?

If the idea of whacking the valves scares you, you should see how a major engine remanufacturer takes things apart! I've always used a socket and hammer to loosen things up before taking cylinder heads apart. As long as you don't go "Godzilla" on them, it's all good.
Yup this is what i do. You could also squirt a little PB blast near the locks(retainers) then a rap with a hammer and socket just to shock em loose then the c clamp spring compressor then I use a magnet to fish the locks. I never want my fingers down there in case the compressor lets loose...
