So, if you consider the port work to bring them from 191 to 225 is worth 1000-1400$, you are in the same range as the AirWolfs were priced at, simply a matter of paying for it, or doing it yourself.

I'm not sure what the best numbers guys are getting from the E-brock Performer RPMs.

I considered the Indy 360-1 245 for my build, but when you add a grand for rockers, and considered the amount of reports I heard from end users having water leaking problems, I avoided that route.
