Mine were used but we're sitting on the new ISKY LDB cam ground on a forged steel core. I believe the previous builder planned to run them "as is" but the engine was never fired. Old valve tip grinders can flat face a lifter but you must go to a a special place to get the radius-ed face found on new lifters. I will save the Isky cam and "unknown" lifters for a possible future budget build.
