Shocks

My current set up for a .333 semi banked asphalt oval, American racer 705 tires,  1-1/4" stock preloaded swaybar, all my springs are 9-1/2" tall with adjustable buckets, I cannot use jack screws and a 6" frame hight rule. RF spring is a 650 LF 550 and a pair of 125s in the rear, my shocks currently are a stock monte in the LF a heavy duty dodge 3/4 ton van shock in the RF, as they bolt right in to the stock monte locations, and a pair of stock monte rear shocks. The shock rule at my track is that I cannot spend more than 90.00 apiece and they must bolt in the stock locations. they cannot be adjustable and they cannot be rebuildable. I want to buy specific valving shocks for each corner of the car. My thinking is LF Medium rebound/soft compression, RF Extra stiff rebound/stiff compression, Both rears soft compression/medium rebound. So, my question is am I out to lunch, or am I in the ballpark? Much appreciation to any suggestions.
