GT40-P: Are new valve springs needed?

[osprey2020]

Hey
Will I need new valve springs in my GT40-P's if I run a Prefomer or Trick Flow #1 cam?
Thanks to all that reply.

rule of thumb, if the cam has over .500 total lift, you will need upgraded springs (preferrably matching) to be safe....

Change the springs, as indyblk5.0 suggested!! Cool??
