Old thread but the info doesn't change.
As always, the laws of physics limit some things from happening.

1 - Seat repair rings can only be used with stock or very
slightly oversize valves in a flathead Ford V8 engine.
2 - Seat repair rings are not needed in any flathead Ford V8
engine except for damage repair. Overlapping rings on
adjacent ports should NOT be done.
3 - Supercharged flathead Ford racing engines running 30 lb.
of boost, 100 nitro and making over 800 hp do NOT run
hard seats. (seat rings)
