Tightening down rocker ladder

[Galway]

Is there a position on engine rotation that no valves are being activated by cams?
Going to fit the rocker ladder after doing timing, and thinking optimal tightening would be with a flat fit down on top of cams without a counter-force.
If there isn't such a position, any caveats?
Thanks as always!

No...there's "always" at least 3 sets of 2 valves open, (or partially open) at any point in the crank rotation in these 16 valve engines.

If the cam timing is correct...it shouldn't pose an issue and the valves will miss the pistons.

Thanks Knobrot.
Appreciate your patience. A first time engine rebuild after cracked piston (replaced all 4).
Yes, I've got TDC and 6mm pins in place, just disliked approaching tightening rockers down with counterforce

Just be aware....If the cams are pinned at TDC and you tighten/torque down the rocker ladder, you "WILL" break something. These engines aren't timed at TDC, they're timed at 50 degrees before TDC on #1. If the flywheel is pinned properly in the correct timing pin slot the #1 & #4 pistons won't be at the top of their bores.

Thanks again.
Me incorrectly assuming it was TDC.
Yes, I have pinned via position sensor hole and 2 6mm pins on sprockets.

Make sure it's the correct flywheel pin.....there's false holes that the incorrect pin can land in, for example the mk7 pin end is slightly different from mk6

Yes, thanks. Got correct position, as locked with timing tool on front end also.

Got it running yet ??
