These Springs are designed to be used with both stock and aftermarket camshafts. The main focus of these springs is to be able to support both higher than stock RPM and boost pressures, without beating up the phasers or needing to lockout the camshafts.

We recommend these valve springs for street / strip applications running no more than 25lbs of boost and a max lift of .600".
