I am trying to find out what the bore size is for these upgraded "Ported Upper and Lower Intake Manifolds" are. I am changing out the intake manifold gasket and I was thinking about taking the manifold to a machine shop to bore it out as well as the throttle body. I know the throttle body is 62mm. I can't find info for the manifolds though. Anyone have the specs? I really would appreciate anyone's help. Thanks.
