Melling Select Performance recommends using Melling MELL-LUBE engine assembly lube during installation to prevent scoring or galling during initial break-in. Do not allow the engine to idle below 1,500 RPM for the first 20 minutes of operation. Always verify adequate valve-to-piston clearance and confirm valve springs do not reach coil bind at full lift when installing high-performance camshafts.
