As usual, if you can give more information, or put names to faces, we’d love to hear from you.
“I think the first picture is No2 machine shop and shows slant4 cylinder heads deing deburred. The second picture is engine assembly and shows the machine which determines the thickness of the shims to achieve the correct valve clearance on the slant 4 head.”
