  • Works as advertised.....but....

    I am using oem retainers on a Ford FE head. The design of this tool is such that the cap will bottom out in mic and not allow you to get a reading. I turned it over and it works okay but no way to get both locks in to check installed height. If you did get both wedged in you would never be able to get apart as again design of tool won't allow retainer to go far enough down to get cap out from around locks. I don't think you will have any issues using one lock to check as long as you take your time and keep retainer level with one hand and tighten mic up with other hand. Still much easier than a ruler and snap gauge.

  • Set it Right

    Very simple and easy to use tool for the experienced racer. An excellent way to set your valve spring pressure precisely!

  • works great

    mic works great, allows for very fast spring measurement. I will admit I was confused at first on the indicated values but realized that the numbers were just a reference and not a measurement. you still need a caliper or micrometer to set the device.

  • Valve Spring Height Micrometer

    Absolutely necessary to easily and properly set proper valve spring height. Easy to take the readings, easy to read the measurement, and very consistent.

  • Just buy a better name brand tool if you’re going to use this at all

    Not accurate at all, for the price I expected better. It’s .030 off. I can accommodate for that but it’s annoying. Beyond that, it says it works on most V8s, but will not work on a set of dart SBC heads. The bottom section is too big in diameter to fit in the spring pocket, and the top is too small to fit the retainer. Small block Chevys ARE most v8s. Definitely wouldn’t recommend.

  • Reads .005" short

    Mic reads .005" shorter than indicated on scale. If I knew how to recalibrate, I would. Otherwise, it's smooth running over entire range, finish is good, easy to read.

  • Nice Product

    The tool helped in selecting high performance springs for my Chevy engine. It took the guess work out of the project.

  • Awesome Tool

    Really makes quick work of setting the heads up with the correct shims for a given set of valve springs.
