Got some more work done on the motor, including removing all bearings from castings, disassembling heads, finishing crankcase prep, and preparing the crank for delivery to the grinding shop.

notes:

• all valve guides worn beyond spec.
• two valve stems show galling and require replacement
• valve seats look good, will refinish with Newway cutter then lap
• tappets are too far worn for me to resurface, will send out for radius grinding
• sludge trap was dirty, but not clogged
• cylinder & pistons are at block shop for bore & hone job
• quadrant plunger spring retainer cap appears to have been hit badly - would not remove with heat and impact. Seems good idea to leave in place as replacement of the spring is not often required, and you can still get to it by removing inner trans cover. Older motors required this anyway.
• cleaned and finished castings with walnut hulls - nice appearance and less risk of abrasive contamination
• rocker box studs and nuts were damaged, and unsalvageable. Will tap boxes to 1/4-20 and install NF/NC studs
