Making a valve compressor tool =)

[Russell]

Hello =)

I've gotta change out my valve seals, and get this engine put back together, and being the poor kid I am, I can't afford to get a real tool, and I'm sure it'll take me longer than a day to replace all the seals, so I need to make a tool of my own, anyone have any ideas for it?

I'm just gonna pull the heads to work on the valve seals, I should replace the gaskets in the heads anyways... Any complications that may arise from such an action?
