RE: Two Valve cover FS 120

The old O.S. FS-120 and the FS-120 Surpass are completely-different designs. The newer FS-120 has a higher compression ratio and different valve timing. This gives it more power at higher RPM than the old FS-120. There are no parts available for the old FS-120, and almost no parts are interchangeable.
