I need to buy a new set of valve springs for my 340. I just looking for a stock replacement set that has spring rates similar to the original factory ones had. Any recommendations?
Valves springs for a 340?

I think it's the same spring and a few $'s less. Someone on this forum pointed out the TF springs being the same comp number with a 16 in front for std springs.

Yep, that is thorough!
These Single-Coil Valve Springs are recommended for 'stock' 340 Replacements.

Same here on the comp cams #901 springs. They have just a little more seat pressure ( 10 lbs or so ). Which I think they needed from the factory to help control the valves a little better at 6000 rpm.
