Camshafts and clearance

I'm talking about the tool that removes the valve spring(valve spring compressor) so you can install a Light spring.........
these are not for the eng, there for You! A spring that is so light that you can push the valve down with one Finger...........................


My buddy has the tool to remove valve springs. I don't have a spring to push the valve down with one finger. I looked at the valve springs on the 915s i'am gonna put on the 340 and they have double springs on them already..I don't think mopar put double spring on a head from the factory..
