Description:

Early engines, e. g., in a Model A Ford, did not have adjustable valve lifters, and instead the valves stems had to be exactly the right length based on the distance from the valve seat to the camshaft, which this tool can measure, as well as measuring the length of the valve itself once it has been set for the desired length.
