Pro Topline Vortec Heads

they say, the heads come with LT1 springs. Does someone know the specs of these springs? and i have seen somewhere, that the lt1 springs are too weak for use with 1.6 roller rockers. is this true?

thanks,
nebu

the rocker has nothing to do with what spring you run, the cam does. match the springs to your cam specs. i'd buy springs from comp or lunati.

You can custom order them with the spring that suits the
job at hand.
If you read the ad "they" recommend that.
You can get the proper spring recomendation from the cam manufacturer.
