Valve spring removel tool

I grabbed this three part tool a long time ago. It has a shaft with two Allen bolts to hold the shaft down in the saddles. The handle is a two part handle.
I made this wood board to mount the head to it and then C clamp it to the work bench.
This works on the bench or in car.

That looks like either the Comp cam tool #5323 or a Proform PFM 67460. The Proform one is about $60.00 from Hughes or $80.00 thru Mancini. I've used one like that many times. If I'm removing springs on a bench I also put a small shop rag in the combustion chamber to keep the valve from opening slightly, air works great if the heads are on the car.
