Slide-A-Links on 66 Valiant ?

Say, I have a turboed 66 Valiant w/ slant 6 that runs in the 11's. This year I added Comp Eng Slide-A-Links to the rear and it raised the whole car about 1". I haven't taken it to the track yet to see how it hooks but is this normal for the body rise? Springs are stock 6 leaf BB from 68 dart. Later.
