     Note:  #1111 inner spring base should be 0.125" taller than the outer spring base.  If your inner spring base is already cut down, order our spacer kit, part number 1714.

    To use valve springs #1103, and #1113, the cylinder head must be machined to remove the step at the spring base and the guide must be cut for positive type seals.  Valve spring #1111 must be used with the spring base step, but must have the guide cut for a positive type seal.  When open pressure on double valve springs exceeds 350lbs, new camshafts should be "broken-in" by running the engine at 2000RPM for 30 minutes and using the outer spring only.  To get the proper installed height using stock or 3/8" stem valves, machining of the spring seat may be necessary.  We suggest cutting the spring seat no more than .030".

    Our camshafts are not comparable to other manufactures and require special valve spring pressures to operate and live satisfactorily.  ONLY USE springs meeting the specifications listed here or on the provided cam cards.  Valve spring pressures and installed heights are supplied with each camshaft.
