Lt1 vs LS1 alignment spec question

After I did my LS1 brake conversion and got it aligned, the caster is out of spec left and right (pos). Are the caster specifications different on an LS1 vs an LT1?

I thought the LT1 and LS1s had the same spec, except for the early 4th gen f-bods that had less caster(3.5 instead of 5). Mine set at +4caster both sides, -0.5camber both sides and 1/32toe-in. The spec calls for +5caster but the steering wheel is easier to turn with 4 and I can't feel any difference in direction stability.
What did your specs show?
