I don't have it yet, waiting for delivery from Rock auto. It's a two bolt flange mount. The Wilwood I have now is also two bolt and I have relocated it four inches away from the engine to gain clearance for the valve cover so removing it to lash the valves is easy. You can see how I did the relocation by going to my photo gallery on here. Going to install the new headers and choose the location I want with the new MC and do whatever fabrication is needed. On another subject, the electrical system worked 100% flawless, your advice on the four pole battery disconnect helped tremendously!, thanks!
