Valve springs / ZZ4 cam question

OK, lets say we have a '94 Vette with an LT1, installed is a ZZ4 cam and LT4 valve springs. With the 1.5 stock rockers the lift is 510. If we went to 1.6 roller rockers the lift would go to 544 ( I believe that's about accurate ).

- Will the LT4 springs handle this lift increase or should the springs be upgraded too?


Thanks in advance!
