Pushrod length was one of the things we explored when I went to competition engine building school.. by adding .050 a pushrod length we gained about .06 at Max lift.But the early and mid numbers suffered slightly... made absolutely no difference on back-to-back on the dyno.. I would say picking a pushrod length with the adjuster set and it's recommended location would be your best bet
