Rocker Shafts- Washers?

The bolts are all the same. The hole up through the shaft is sized to allow the oil to feed up around the bolt shank. I did find that one set aftermarket shafts had smaller holes at all points including the oil feed point (2nd stand from the left when looking at either head).

Big mounting holes in the shafts allow the shafts to shift each time you install, making consistent setup of the shims difficult. So it may behoove you to make some marks on each shaft and 1 or more stands on each side to align the shafts in a consistent position each time, so the shims and clearances line up the same each time.

Ah, I was gonna say, all my original bolts are the same. All of the Angelucci bolts are the same, too. I had a 383 and a 340 yeeeeears ago, and I don't remember those bolts being different. Cool.
They are factory shafts, but I will check them for larger oiling holes.

I'll consider the shaft movement and mark accordingly. I'm going to stencil all of the stands today to be sure they are installed in the right location after they are milled. There's not much coming off, maybe they'll grind them. Though, I've heard that aluminum clogs up grinding wheels and they tend to blow up. In my tool and die days, I never worked with aluminum.

Thanks! (Nothing like a good behoovement.) :)
