There is a set of new Miller Mid-lifts on ebay right now for $2950.00 (ouch) He says he has 4 sets?
BDS sells a 8-71 blower manifold for stock style Boss '9 heads.
C and C Motorsports makes a blower manifold for AR/RCI/C and C heads.
I have built several Boss '9s, The last one was blown using an original Mickey Thompson magnisium blower manifold from his funny car days. I used stock intake rockers and Miller exhaust rockers on that motor.
Jesel and, I believe, T&D make (or made) rockers for stock, early AR and then the later AR and RCI heads as well.
These are not bolt-ons and require plenty of machine work to fit
Check with C and C Motorsports as well. They have everything you need to build an all aluminum Boss '9.
