You can refinish some tool steel lifters to allow them to be used on a different camshaft, they must be sent back to the lifter manufacturer. In order to be able to move a tool steel lifter to a different camshaft or lobe, it would need to be DLC coated. You cannot run DLC coated lifters on a cast iron core cam. You can use un-coated tool steel lifters on a cast iron camshaft, whether the camshaft has been nitrided or not.

I use Trend lifters.
