So I did.

Some people have fabricated the tool with wood.

I believe the tool helps keep the cams from moving when you remove the cam gears.

Not saying he should, just saying that is when I have seen the tool used. Sorry if I was not clear on that.

You don't HAVE to have the tool. It makes it a lot easier, but you don't HAVE to have it. Basically, the tool helps separate the top part of the head from the bottom part. A 3/8" ratchet extension can be used if you're careful, or make something out of wood. you pry gently in the areas cast for the tool, and it will separate. Then, when putting it all back together, if you don't have the giant wing- nut device to press the cover back down, you press it back down with the bolts. Install them all hand tight, then tighten them in sequence 1 turn each until the top meets the bottom, and then torque them all to spec. Yes, this take a good bit of time, but unless you do a lot of them, it's not worth it to get the tool.

As for the cam gears... DO NOT take them off, unless you're prepared to realign the cams, as the cams aren't indexed to the gears. If you absolutely need to remove the cam gears, make sure the cam is in a "safe" position, get the engine to where none of the pistons are at the top, and mark the gear in relation to the cam before removing the bolts. But in general, DON'T take the cam gears off.

The tool FCPgroton is talkng about is something that IPD sells to keep the cams in alignment when changing the timing belt. That can also be of help when putting the top cover back on.
