I will add my 2 cents to this as well, I have a 408 LS in my 95, I am running the TSP 228R 588 lift intake and exhaust with 110 LSA to bring in torque at lower rpm since this is a truck, I have a built 4L80E with Transgo HD2 shift kit and 2400 stall converter. Makes a ton of power and lot's down...
I have 2 set's, 1 set is out of a 99 Denali, they need recovered and the 2nd set is out of a 99 Escalade and they are light tan and in good shape, both sets are 6 way power with heat. Which set are you interested in?
