I have the experience. And I advised that you should reconsider. I did not tell you to do anything, or insist that you do it my way, I advised that it was not the best or even a good alternative.
HRL noted one of the issues with a dual point, getting both sets of points set up correctly. Dual points require frequent adjustment because they frequently go out of adjustment. That is from my experience with the Mallory. Then your motor runs at less then optimal efficiency. That has also been my experience. You were advised by a number of folks to reconsider the dual point and think more in terms of an HEI.
