oversized eccentrics Upgrade/Performance Oversize eccentrics are often required to adjust the valves to spec when using a cam with a smaller base circle (typical on regrind cams). We like them better than lash caps. These eccentrics work on M10, M20 and M30 engines. Specification: .028" additional adjustment at the cam.
