Magnum Head Valve Spring Compressor

It is easier to use the 2 jaw style with the handle on top and use a hose clamp to keep the jaws from popping out.

I assume you mean the screw type like I showed in post #9?

I'm a little concerned with trying that one since both the springs I am removing and the ones I am adding have a flat dampener. If those are tall enough, it could cause problems with trying to get things compressed.
