I'm not familiar with that particular head, but you can probably leave
the valve springs on when removing the head. You will probably need to
remove the rockers, but then the head should unbolt, and you can pull it
off the block. Once you've got the head on the bench, it'll be a lot
easier to remove the valve springs. Yes, you will need a special tool,
called a valve spring compressor. You can probably borrow one for free
at a local parts store. (Autozone, etc.) Usually you give them a
deposit, and they give you the tool. You get your money back when you
return the tool. You also have the option of never returning it, if you
want to keep it. The general procedure is to support the valve from
underneath the head (I use a wad of rolled up paper towels), put the
compressor on the valve, tighten it up to compress the valve, then
(if necessary) tap the top of the compressor with a hammer to break
the retainer free from the valve. I usually use a magnet to suck the
keepers off the valve, then you can remove the spring and retainer,
and drop the valve out through the bottom of the head.
For a step by step procedure using the Autozone tool, go to
