Valve Springs:

I made mine out of low density foam (I used foam from a camera travel case). Squeeze down a half inch thick piece of foam with a suitable diameter socket and run a sharp blade around the perimeter to cut. I used a sharpened piece of tubing to cut out a central hole for the valve stem. See photo under "Made" tab.
