Ready to call it a wrap, tool looking really good so far.

Actually serves more purposes than I even realized.

Can verify in a matter of minutes, maybe 5 or less, any variations from the top horseshoe groove to the spring seat register, easily.

I really never give this area much thought, it doesn't hurt anything in the larger picture. It does help explain some the number of various shims needed on ass'y from valve-to-valve??

Thanks, Gary in N.Y.

P.S. Here's a series of 4 photos, ALL original Flathead guides (no aftermarket, none damaged) showing the difference between only these 4. I checked a dozen aftermarket pieces from 2 different batches and they were within about .002" of each other! Only the OEM's are all over the place!
