Looking at the cylinder head cc the 461x is listed as 172cc intake and 64cc exhaust. All others are 165cc and 65cc. But then there is a note that says port volumes based on "X" head. Does this mean for example a 041 head can be 172cc intake port?
Also what is the best intake to use? I have a 3875954.
