"596" Head Valve/Valve Spring Questions

PRH said

In your opening post there was talk about different valves, etc.
Get all of that sorted out first, see what the available installed height is, and select a spring that fits the heads…… that’s suitable for what the cam is.
You don’t need springs that until it’s time to assemble the heads.

The springs are the direction people took when replying. I'm not going to spend $400-500 to get the heads prepped for 2.02 valves, so I can figure out what springs to get, only to find out that I just bought an extra 10 horsepower and didn't need to go that route for my power level. Kind of putting the cart before the horse, don't you think?
