Brodix B1BA heads...

Got a good friend running ported B1BA heads on a 70 Duster
3100 pounds with driver. Roller cam( low 260’s@ 50)
Hair over 12 to 1. 904
Been 10.20’s at 128-129
My brother also has a set ready to go on his 66 Dart real soon replacing Eddies. Stroker as well with flat tappet cam.
I would rate well done B1BA’s slightly better than well done Eddies. Maybe 20-25 horse better, all things being the same.
