Valve springs question

1938dodge said
I’m doing a fresh up on my LA 318 just purchased the SPD 25 cam with new lifters and push rods.
My question is I have a complete set of P4120249 springs that have been sitting in my garage for a while now.
With this new cam and everything else being stock should I use these springs or stay with the original springs?

203°/.410 You could use a stock Melling spring. Their 340 spring is #466434 (recommended for their MTD-1 and 2 cam which is their versions of the 340 cam.)
