That's a race head. I'm sure the thought process is there is little but B1-BAs as an intermediate between the street type heads (RPMs, Indys,W2/W5) and the exotic race stuff (W9,Pseries). Note the choice of lifter angle, the threaded coolant passage points for additional coolant flow, and the 18-bolt potential. It's not a street head.
As far as aftermarket... They ALL are like that. They ALL need to be checked and corrected. Tehy will bolt on, and they will run in many cases better than a non-performacne oriented shop's basic repair/rebuild factory heads will. But, as far as what I want them for, that means consistently fixing the too-tight guide clearances, replacing the springs, having an accurate 5 angle valve job done, fixing the cut on the valves, and having the decks cut properly. I also will hand blend and gasket match. Usually the total cost for a set of RPMS, ready to run to my standards, is $2500. I'll add Hughes is, in terms of machining quality, just as bad and Indy is worse...
I liken it to Denny's telling me how good their food is. It's food I don't have to cook and can eat without getting sick. So it's defiantely food, but as they sell it - not good food by my standards...lol.
