Measuring valve guides

[Carlyle]

These would work very nice for measuring valve guide to stem clearances. I hate those T gauges that you measure with a micrometer. Only 2" depth so you may have to reach in from both sides.

Brown & Sharpe Intrimik Hole Gauges

Read measurements directly from these gauges without the need for a micrometer. Three evenly spaced steel contacts ensure proper centering. Gauges have a ratchet thimble and measure in 0.0002" increments. Also known as bore gauges.
