If you can use a universal valve spring compresser, it will cost you about $50 (NAPA). YOu can use an air chuck on the cylinders. However, you can also keep the vales up by putting each pistion TDC when are working on that particular set of valves. I would advise thi spractice anyway. If the cylinder leaks down while you are working on a valve, you could lost it in the cylinder.
