It really depends on the ramp angles of the cam and the year of the heads. The newer heads have some really good springs. If you think about the TW-777, TW-7H or something like that, usually the springs are good. If you are asking about a 103 engine, I'm going to assume its a later model with the better springs.
It is probably best though to look at the cam manufacturer's recommendations or talk with your engine builder or parts supplier.

TMan is offering a 600 Supermax cam for stock heads/springs that sports .600 lift. I've had very good results with Tman cams but I have not ran this particular cam in anything yet. Call him up and pick his brain...
