Looking for Alignment Advice

I did some skimming through some previous threads.There's a bunch of good info already.

Right now I'm at factory specs & it sucks, I think that the caster is not positive enough. It drives straight as an arrow on good roads & seems to corner well, but when on roads that are not flat (truck grooves) it really sucks. At this point I'm thinking about leaving my ride height where it is...just a bit above stock. With the Just suspension torsions the car doesn't "dip" much. Which will help a bunch in preventing my headers from getting scraped.

The specs I think that I'll have them shoot for are:

Caster: Left +4, Right +4.25
Camber: Left & Right -.25
Toe-In: 1/16"
