do i raise or lower ride height to get more

The service manual tells to measure the distance from the floor to the bottom of the ball joint, then measure from the floor to the lowest edge of the adjusting blade (thats the "cam" he was refering to and is in between the edges of the control arm. The difrence from the inner height to the outer measurement (ball joint) is supposed to be 1 7/8" +-1/8" (for 73 Dart Swinger, yours may be slightly difrent height requirement) to be at factory ride height, but u can play with it a little more than that, you just have to be sure to get it aligned when your done, also all measurements are done with the vehicle weight ON the suspension so you have to measure it while laying on the ground. Also dont worry about the bolts being the same side to side, actual ride height side to side is way more critical than how much thread is sticking out because if your bars are factory original one may have twisted more than the other over the years.
