Valve Spring Height Micrometer Question

Jeremy K · 07-04-2013, 04:09 PM

I have the 4930 height micrometer and it works with those retainers. Although, the bottom bore had to be ground out to clear the part of the valve guide that wasn't cut down for the seals. Your heads may be different.

Use a .060" spring shim that has an I.D. big enough to fit the inner part of the retainer and a large enough O.D. to fit the height mic. Then add .060" to the mic. reading.
