Na, it's actually a 75 degree cut inboard of the seats, but any good machine shop he brings it to will know what to do. Also have the valves back cut if they have the ski jump lift on them. Remember you ALSO want a lot of flow very early in the lift just as the valve opens to fill that 365cid engine. Chrysler. put the 2.02 valves on the 340 for a reason and your build has 25 more cubes, headers, hi flow intake, and more HP!!
