    LT1 valve springs

    What outter diameter valve springs can be used on the stock lt1 heads? 96 Z28. Found a new set of dual springs, the outter diameter is 1.437. Car has 174k miles and they have never been changed out, plus planning on upgrading to larger cam soon, wanting to get valve train ready for it.

    I wouldnt worry about changing out the valvetrain until you actually do the cam. And dont pick out your springs until you get the cam, because there is such a thing as too much spring, even for a roller cam.

    Like 5.0 said pick your cam, then we'll talk springs. I would also consider roller rockers, caps, keys, shims, lifters and rods. Not only for convenience (since its going to be apart) but because of mileage. I know this is added expense but seriously, consider it.
