PI cams and springs

[tjmaxx]

I am looking into buying some PI cams with oem valve springs and 10mm bolts, They have 45k miles on them. I dont have to have them shipped because I can pick them up. He wanted $125 for them, and I got him down to $100 does this sound like an okay deal. How much power can I expect to gain from these in my 96 GT?
