If you were only going to open the head port entrance without addressing “the pinch” I honestly think you are doing more bad than good.

Is the "pinch" on small block Mopar heads that area where the pushrod holes are drilled? in the center intake ports? The 340 TA heads i believe they moved them out so that area could be ported.
