What to do?

I have pulled the engine out of my 91 gt and I just got in a few of the new parts I ordered..

Here is the question.... I now have bbk long tubes, H-pipe, gt40p heads, 3.73 gears, new clutch, short shifter, cai, and throttle body. I am planning on ordering an e303 cam but wanted everyones opinion on that... Would you just put the cam in or do new springs as well? All opinions appreciated
