    To use valve springs #1107, #1109, #1117, and #1119 on OEM iron heads, the cylinder head must be machined at the spring base and the guide must be cut for positive type seals.  When open pressure on double valve springs exceeds 300lbs, new flat tappet camshafts should be "broken-in" by running the engine at 1800rpm for 30 minutes and using the outer spring only.  Roller camshafts do not require break-in.

     

    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.
