I have see the cool tool Blackroadster has for helping with a timing belt change. (see below)
I have also seen the 2 crescent wrenches tied together with a clamp to hold the cams.
But is there a tool (or better yet a drawing of a tool) to hold the cams in a similar setup to the 2 wrenches and a clamp method??
