6.0L Head/Rockers Install Help

[KCS250]

Putting the heads back on a 2005 6.0L motor.
Manual states to rotate crankshaft until dowl is at 6 oclock position, then tighten down the rocker fulcrum bolts.
I can't see dowl nor have ability to rotate crank.

Thinking at 6 oclock some pistons are top and other two at bottom. Manual only has you place crank at 6 oclock once per head. so not sure what this does.

Currently the pistons are near TDC and bottom. Is there away to install fulcrum bolts without rotating crank?

Thanks,

I have 30" of snow on the ground will likely be working on this tomorrow. With both crank positions two pistons are up and two are down.

Seems like 6 o'clock and 12 o'clock are the same, in either position some valves will be compressed when tightening the rocker arm fulcrum bolts. The service manual must say this for a reason.

It is so your valves are in the proper position for tightening.
