ill be devil's advocate. I just ordered 4 2 piece ss valves from proflow for ~$9 a piece. I think 2 piece valves are super easy to take apart (less parts and such) if you have 2 crescent wrenches and some elbow grease they come right apart. Save the money get 2 pieces because they function exactly the same as the 'bling' ones and bling out another part of your rig.
