ford flathead adjustable valve lifter holding tool.
This tool hand made in California was designed to hold a adjustable lifter to prevent damage to it when making adjustments. Pinching a lifter in a vise without this tool will oval or mar a lifter. I prefer to use this method vs drilling a engine block or using the cheap valve adjustment tools that break or simply don’t work at all. Setting lifter height on the bench before installation is key. Simply tighten the bolt on the tool against the void space on rocker to secure it. Tool has a plastic liner to protect the lifters polished surface from damage. Lifetime warranty on the tool.
