Stronger beheaded Pitman or not?

Hello dear Schraubergemeinde. My Suzuki now also gets Nole feathers + 5 and OME ́s. At the moment there are still extended heel slopes in it and for the future I plan a bodylifting. From how much cm height it is advisable or necessary to install a beveled or more beveled Pitman arm? Is the original arm actually straight (flat) or already crooked (how much) ? MfG Pete
