WOW! That is a lot of lifter info. Thanks. These are the same as GMC aren't they? I remember in some ancient GMC performance build info, maybe Bill Fisher, it was recommended to use used '39 Chevy lifters that gad been hardened through use.
Yep. It seems that the Chevy engineers collaborated with the GMC engineers on the milk bottle lifter design - though GMC shipped it first in '39. Here's an aftermarket example:
I don't have this set in hand - or I would have measured and weighed them. The packaging is '59 or later as covers the entire date range that GMC made these engines. The earliest cross references suggest that the 235 and GMC shared a common lifter.
As far as California Bill's preferences - his book suggests used lifters because of (as you say) work hardening. As for the early Bucket/Cup style lifter - Bill was also a fan of Barker High Lift rockers. With the longer push rod they don't tilt as far off perpendicular.
