Is this to much cam

For $50-60 he cam put a fresh set of 340 springs on the engine. Smart money to spend.

Under $4 at summit too IIRC, buy another 50 in parts and you get free shipping.

Yes, something like those... they don't cost an arm and leg. There are a lot of good single spring sets in the $60-80 range for a full set.

To to OP, now that you are considering new/better springs, now I'd be re-looking at the cam. Something with shorter advertised duration but about the same .050" duration. Like this:

The shorter advertised duration ought to keep your low RPM torque up better and that is important for most trucks, especially when starting with low CR anyway. Yeah, I know mission and price creep...just opening up some options.
