the B-series won't fit for sure. A H23 manifold will bolt up to a F22A1/2 head, but the ports are a lot bigger, so the head will need to be ported to match the IM. Also, there wouldn't really be a point of running an intake manifold with larger ports if you dont need it. Unless you are running a monster cam and very high C/R pistons, you will probably not outflow the stock F22A intake manifold. If running a turbo, a larger intake manifold means more area to pressurize when reaching full boost (may cause more lag at low rpm)
