hey guys, has anyone done this? ie RB20 head on a 30 bottom end? im aware the the smaller ports and valves wont make as much power per psi as a 25/26 head, i assume the chamber diam might also be wrong but im sure it could be ported out a touch to suit. i would think this combo would make awsome low down torque, especialy if it was fitted with twin t28s etc
is there a reason it wouldnt work that im not seeing?
cheers in advance
