The interesting thing about ignition systems is that if there is enough juice to fire the spark plugs, then that is all the coil will put out. Since yours fires well above 2000 rpm when the boost is increasing, it is OK voltage wise. That does not mean there might not be a timing problem or an errant spark causing a misfire or backfire.

But do upgrade to an aftermarket distributor when you can. I don't think that any HEI will clear the blower. I would avoid magnetos. When you upgrade ignition systems, do it as A SYSTEM... get all the components including plug wires from the same manufacturer. I would go MSD.
i would get a msd 6al box for the distb. then i would get a fuel regultor on it and set timming to 25 deg total with the coldest plugs i could find
and i would run a 36 slug on the bottom run it at 5 % under
