diff between V8 and I6 coil springs?

Hey Guys,

Is there a way to tell the difference between '65 I6 and V8 springs? The PO of my t code did a half-assed job with the V8 conversion (basically only changing the motor and putting in 5 lug front discs). I've corrected the steering components, tie rods, etc to bring everything up to spec, but am unsure if the car still has the I6 springs. Any quick way to tell? The front end sits kinda low, which is why I'm wondering. I like the look, but want to make sure all's safe.

Thanks!
