Read to get my heads ported they are Dart 230 23deg, the head never been touch. What shop would u guys recommended thanks.
such as what ? if you looking to build a 23* combo and want an all out deal then your not going to get a CNC ou tthe box headAll i'm saying is after paying for the port job, mabye some bigger intake valves, cut the seats, new springs and possibly gain 40-50hp. Estimate putting $2000 into the heads I might consider other options. Good luck either way.........
