This thing comes in two sizes. The only difference between the two is the rubber tube in the middle. It works ok. There are other better methods.

It cut my setup time down to minutes from hours and I checked an engine that I had done just to find I was off by .050 so it is more accurate than the old way. Definitely worth the money because time is money.

This thing is accurate. I checked my geometry three ways. I did the die on valve tip and found a center mark with adjustable push rod. I did the 90 degrees to the valve at half lift theory and I used this checker.I did this specifically to check the accuracy of this tool and it is dead on

Great tool! I used with an adjustable pushrods and the marker method to check geometry. I didn't rely on this single tool but provides more confidence with other verification methods.
