Roller cam HD valve springs

Hi guys im looking at upgrading my valve springs on my roller cam vs 304 to something a bit more HD so i can up the psi on the supercharger.

Does anyone have any recommendations or words of advice?

Im not looking at machining anything.

thanks

Have the spring pockets in the head been machined at all?

What springs does it have now and what are the recommended springs for the cam?

No it is standard atm no machining just running a senator cam in it and standard springs.

LT1 valve springs are a fairly common upgrade spring for performance cams, fit in the standard spring pockets etc.
