SB Performer RPM intake

Ever since the Performer RPM Air Gap came on the scene, the standard RPM droped in stock and fetching price. Couple pictures might help out. Still a good deal and a great intake, especially if you have shaved heads and didnt mill the intake side of the head. Hmmm might be shaving my J heads .040, something like this might work out instead of milling the intake side. I'll have to reserch that.
