I read about just buying standard 3/8 brass washers and stacking them 2 high. Would this accomplish the job? I just don't want to spend $5 a washer plus shipping when I could just buy those at the store. Any reason why one would avoid doing that?

Question on sealing washers (4 outer ones on top)
- Thread starter JE4570

nope.
I have the feeling steel washers would work too. Any oil there is not under pressure plus it would be flowing upward... Brass/bronze isn't malleable enough to do much sealing anyway. Where there are copper washers, different story tho.
interesting. I’ll probably give the standard brass washers a try unless anyone else speaks up against it. I may put some sealer in between and on the bottom for good measure, but it sounds like it isn’t terribly critical.
I found the copper washers at my local Ace Hardware. If I recall... they were just under a buck apiece.
Years back, before Mike's sold the brass washers, we used these copper Suzuki washers .....

The outer stud holes are in fact pressurized with oil... Yes, it's a small pressure... but enough to weep oil if not properly sealed.
Rocker shafts are pressurized (from the oil tube) to lube the rockers and valves. The rocker shaft bore is drilled right through the outer stud holes. Between the head and rocker box is 4 o-rings at the outer stud holes... for the same reason.
Yes, the oil squirters are at the base of the rocker arms, aimed at the cam/pad junction.
The rocker shafts aren't drilled all the way thru. Whatever oil pressure gets to the outside shaft boss comes from the thin fit of rocker to shaft.
Another source of pressure to that narrow zone, between the side of the rocker and the outside shaft boss, would be from crankcase venting pressures...

Worst feeling In the world is snapping a bolt or stud because you cheaped out on a crush washer before you torqued it down.
