I bought a Stealth and returned it. The current Stealth is the same manifold as the Action Plus, except it has a square bore carb mount instead of a spread bote. The port outlets are 318 size and the one I got had some core shift. I was disappointed by the quality and returned it. I wound up finding an RPM online at O'Reilly Auto. They sent it to my local store. It's worth checking if they still have them. They had RPM's and Airgaps both listed in stock a couple of months ago.
