Flat head motors have a large quench area which creates a propensity for carbon build up.

However, before I start adding on gadgets to remedy motor noises I would look over the other systems. For example, if the dwell is not stable due to worn parts, or the advance curve is wrong that can cause problems. Another problem area is the heat stove under the carburetor which clogs up with carbon and inhibits vaporization.

There are three add on gadgets that could be used to reduce carbon build up and associated motor noise. A better air cleaner, a PCV system, and an EGR.

The first is easy for a do it yourself project.

The second requires engineering, but addition of a crankcase air pump would achieve same but forgo recycling of waste gases.

The third would require carburetion changes to accommodate a ported vacuum source for the EGR controller.
