Normal 250 head = 1 1/16" inlet bore = Amal 376 carb
CSR/350 head = 1 1/8" inlet bore = Amal 389 carb
If you just want to get it running and aren't too fussed about getting the specs exactly right then either head will work. However, it's important that the carburettor bore and inlet bore match exactly (otherwise it'll run terribly).
Maximum power will be slightly reduced (compared to a CSR) with the smaller bore head, but probably not in any noticeable way...
