    Q:
    What should you check and how should you correct the valve spring height during reassembly of the Cylinder Head for the 1993 Chevrolet Beretta? Posted by Herion B.
    A:
    Check the installed valve spring height with a ruler graduated in 1/32-inch increments or a dial caliper. If the head was sent out for service work, the installed height should be correct. The measurement is taken from the top of each spring seat, rotator, or top shim to the bottom of the retainer. If the height is greater than specified, shims can be added under the springs to correct it. However, do not shim the springs to the point where the installed height is less than specified.
