Hi List, 
I posted this to 311 also, but thought i would try here too. Which of the following tools would work the best for an on the car valve spring removal? This is a Sears link showing many different kinds of compressor tools:

It is a 1600 and No the head does not need to come off. I want to put some valve seals in this weekend but have never done that before. I know the steps but getting a compressor to work is the main problem.
Thanks!
