Now that you have the PROFORM Valve Spring Tester you'll need a set of PROFORM Air Hold Adapters to remove your springs with the heads on the engine. It's a simple 3-step process: screw the air hold adapter into your spark plug hole, attach air fitting, and then an air hose. The air pressure will hold up your valves while you get to work!
