PRB intake manifold + P2R expansion chamber

[D R U]

Do you guys think the PRB IM + the P2R expansion chamber* is a viable alternative to an RBC IM?

Im in a position to get a PRB IM at a good price, so im looking at this option.
And the RBC has gone up in price a lot since the dollars gone down.

Also does anyone know if the PRB is bolt on to the K24a?
