Torque Spec Question. 120-130

Sure. They are all the same (B16, B18, B20 and B30, anyway)
I'm not sure the direction is important but you start with the two bolts
nearest the center and then alternate front and back in a spiral pattern
till you get them all. Then go over in the same order at the next torque
level, etc. I usually go around twice at the highest level and sometimes
I get some more takeup which I conclude is gasket compression.

I've noted with the headbolt-mounted idler bracket that the bolt heads
are usually 5/8" where the OEM headbolts are normally 11/16", which gives
a bit larger clamping surface engagement. Also the OEM bolts are usually
necked down in the center, which is also a good deal since otherwise
the highest stress is at the root of the first engaged thread.
