I'm currently using a FSI on my speedster with my BRIERLEY head. It requires less advance than other performance heads. FSI is a delight to work with, tell them you are running one of my heads and they will set their dist. to match what I want, max of 10 degrees in the dist., 20 at the crank. The one thing about the FSI is that you should run power to them thru a separate, independent switch from the batt, and a direct ground wire to the batt.
I have run Mallory/Datsun dual point distributors in my OHV engines with great success, they require a slight amount of machining to fit in the head and a new shaft, both easy to do.
I ran a B dist. years ago, and it ran well but on a dist. machine the cam showed wear, so it didn't fire at 90 degree intervals, and on the one I had, the advance was unlimited, no problem on a flathead because they don't rev very high.
