keep an eye on the distance between the bottom of the shaft and the (5) saddles & tighten the bolts evenly so the distances stay the same as you tighten em down a little at a time. What Stump said, some valves will be free (& their respective bolts will turn easy) and some will be under tension (& their respective bolts will turn hard) but stick to the plan & keep the gaps even, as they decrease with turning the bolts down

Also make sure all pushrods and rockers line up correctly and are seated before beginning to snug down the bolts. Agreed, & a thin straight length of non flux coated (bare) welding rod wire is good for that

I take the oil dipstick out and lay it across the rocker pedestals to hold the pushrods aligned while tightening the bolts down That's a neat trick. I'll have to remember that one.
I have mechanical Aptitude. I can screw up anything.

I finally was able to see the pictures ...
The rocker shafts will not sit flush against the pedestals when you are assembling them onto an engine that has a CAM AND LIFTERS installed because all your valves are CLOSED and some of them will be OPEN, to varying degrees, once the shaft is torqued in place.
Do as stated above and make sure the pushrods are in the right postilions and slowly tighten all the bolts one by one , end to end till you get the shafts against the pedestals then torque them to spec .
running up my post count some more .
