The K&B 7.5 can be easily converted to sub 22K use, by simply dropping the sleeve and raising the head accordingly, to decrease the exhaust timing to about 160-165ยบ.
It will still respond well to a (longer) tuned exhaust. The mini-pipe in FBD's post will also be usable.
well that then defeats the purpose of getting this engine in the first place..
