Brake bleeding instructions
Just to make your heads explode, these are both excerpts from Oldsmobile factory-issued Chassis Service Manuals. 1970 on the left, 1985 on the right. Note especially the part in the 1970 manual about "bleed the master cylinder last".

This same discussion is taking place on the AACA forum. This is from a 1969 Motors Manual. Note the GM bleeding orders, considering that Chevy cars for the most part used exactly the same brake system hardware as did other GM cars of that period. Clearly it doesn't matter.

I certainly haven't seen everything, but I have never seen a master cylinder with a bleeder valve in any brand.
I too was taught closest to furthest.
This is of course unless it is a volvo 240 then:
1. Left rear
2. Left front, upper, inner
3. Right front, upper, inner
4. Right rear
5. Right front, outer
6. Right front, lower, inner
7. Left front, outer
8. Left front, lower, inner

I just got home and for my sanity I checked my Sonoma a Monte Carlo, our 61 studebaker, my 55 Chevy truck, the 64 cutlass and a spare master I have from a 70s Chevy truck
None of them have these bleeders but even my older gm stuff all have replacement masters on them.
would this be something that was dropped from the castings for aftermarket replacement parts?
ive always just bench bled the master and
put it in the car while trying to hook up the lines as fast as possible then bled the brakes at the wheels
I feel like I’ve missed out on a whole new
thing

If you install a new master or rebuilt master bench bleed.
I never had a problem getting a solid peddle using this method.
