I try to assume nothing but #1 on a flathead is the front US passenger side cylinder. People who are used to modern engines often get that wrong. Also, as far as I know, a flathead is the only v8 engine where #1 is not the cylinder farthest forward.
As others have stated, moving the distributor gear a tooth at a time or ditching the Loadmatic for something better like B&S suggested will probably fix the problem. The stock distributor uses vacuum from both the carb and intake which is a problem with a non stock cam.
