I don't think you are going to find any Saito valves that will fit your project.
FA-150 valves are .542" in diameter. The bad news is that they are only 1.252" in OA length. This is the smallest valve head in the big block series (same as the FA-120S) and yet the OA length is too short.
You might find medium block valves W/a diameter that is close enough to grind to spec, but then the OA length will be even shorter.
