V100 engine: what carb and exhaust? what jetting

I bought a v100 engine to replace my 50 special one. It came without a carb and without an exhaust. I have a new sitoplus for the 50 special, is it the same size as the v100 one? Which carb should I use? There`s still a manifold attached to the v100 engine, will this fit ? any advice on jetting?
many thanks,
