The Seller ended the eBay auction and later decided to sell me this lot of forged rockers and shafts. I actually was more interested in the tools than anything else since I have too may forged rockers as it is.

This is the specialized Mitutoyo dial-caliper https://pbase.com/9146gt/image/147105562 tool used to measure the thickness of the lash caps. Each lash cap was originally scribed with their individual thickness, but over time, and sometimes in a hurry, engine builders not having the correct lash-cap thickness resorted to grinding them down to obtain that exact measurement. You can no longer trust the thickness number scribed in them, verification is an absolute must.

These the other specialized tools https://pbase.com/image/147105564 use to R/R and service the lash-caps more easily. The tool clamps down on the cam-towers and used to compressed the valve springs.
