Front Springs: What to buy??

[cabech984]

I am in the market for some new front springs for my 90 Firebird. It sits lower in the front since I swapped the 3.8L V6 into it. It was originally a 3.1L V6 Car. Should I buy V8 Springs or V6 Springs? What does the TTA have? Part numbers would be great too!!!

Thanks!
