Dual Spring Backface cutter???

Your best bet is from an individual that don't build flatheads anymore. The size you need is a .940" and has 4 flutes.
 
7/8 reverse spotfacer with a 1/4 pilot. brown aviation tools. you'll need to get the pilot to under .250 for a race motor or you'll need to ream the hole to .250+ and cut before you intstall guides. fyi
 
Yeah I’ve as in the same boat for tooling but with luck I was able to buy out a Retired Flathead builder for his tooling. Best bet is to scout market place or head to a track and ask some of the builders for old tooling.
