Stealth, RPM, 906 heads

the real purpose for the 906 heads is if you are doing a perfect resto for 68,69,70 B or RB

chrysler put them on all the big blocks those three years. it would be worth it to have them CNC ported if you had a 69 R/T or Dart GTS or something

the RPM's and Stealth are great for medium builds. i think the torkers are for all out race. the indy's are very nice heads too. just gotta be careful which ones you get because of the maxwedge size ports and stuff you might end up having to buy new headers intakes etc.

port flows are nice on most of them
