I wouldn't really call 440-1s "big boy pants". I think that would be more like B1-MCs or possibly Predators. In my opinion, unless you go to a serious head, the gains over what you have now will be little compared to money spent. Are the SRs fully ported, with Max Wedge size ports? If not, that would be a bit of a gain and require only a manifold change
