I took pictures the best I could while assembled but want to make sure I don't miss anything or get in the wrong order.

Figure 18 on the same page shows the rocker assembly - 4 distinct parts, 3 of each, left and right intake and exhaust - that have to be assembled in the correct order on the rocker shaft. | | | | | Joined: Jan 2020 Posts: 96 'Bolter | | 'Bolter Joined: Jan 2020 Posts: 96 | I've seen that picture but thanks did reminding me of it.. One thing I need more detail is there are so really thin washers below the valve spring (I think) and half of the caps on the valve spring that hold the retainers can spin..

The shims may or may not be all the same thickness. Check for correct spring height... that should correct the loose caps if the springs are the correct free length, as they should have a minimum closed tension of 55lb, +/-, higher for newer 235s and 261s. This table may help, from Pre '68 Dave's blog: Valve Spring Pressures and Installed Heights.

It was too tough to use those pictures alone. Many rockers have numbers on them, that's what unlocked the secret for me. I found out from this thread: https://www.chevytalk.org/fusionbb/showtopic.php?tid/257275/Rear RE LI RI LE RE LI RI LE RE LI RI LE Front Rear 8, 5, 6, 7, 8, 5, 6, 7, 8, 5, 6, 7 Front Note: my old rockers had an extra 8 in front of all those numbers.
