You used to be able to get 1.250" inlets from Mini places but these valves are scarce now.
Check all the locals, and Minispares UK etc.
The last 295 I did like that I used 1100S inlets (33mm) and exhausts (29.4mm) but you need to turn the exhausts down to 27mm or they hit the block.
Note both these valves have longer stems and the 1275 narrow groove collets. It's not a cheap way to do it.
