Porting a Trick Flow intake

[bigblockcoupe]

are you running stock heads? if so porting isn't going to do a whole lot if anything and it could actually hurt your performance i think the ports on the tfs intakes are already a little larger than the factory cast iron heads and if you port them out a little more what you end up with is a lip that the incoming air slams into going from the intake into the head if your serious about porting then get a good set of aftermarket heads or have your factory heads port matched to the intake.
