depending on your tuner and the condition of the motor, and how you drive it, it will last, but yes you need to do springs

With 12psi boost on the back side of the intake valve you have 30lb less valve spring pressure, you're probably going to rev it harder, and how many k's have those stock springs already got on them.....
Yes you need new upgraded valve springs

Its very hit an miss with these motors some are ok some not so great, mines a unopened unknown kms ba n/a motor with 12psi on stock springs, I think trick is to keep exh back pressure as low as possible. Makes 290rwkw and 11.4@121mph. Springs are cheap they are just a pita to fit.
