So is it head up or down?
I keep mine neutral normally?

Judging by IC's reply, head is to inline with your spine at all times.
So it's a lifting aid? Better mention it on the PB chart.
FF, looking up is actually worse biomechanically (although not worse than looking down so far that your upper back bends). It's something that's only recently started filtering through strength and conditioning channels, but most of the top coaches are advocating a neutral spine which includes packing the neck and tucking the chin. This basically means you initiate the deadlift looking at the floor, but the idea is to keep your spine aligned and not fix your eyes on a static point.
People tend to look up to reclaim stability in their spine due to having poor thoracic mobility or weak erectors and mid/upper back stabilisers.
Edit: it's also just a fact of modern life that most people spend most of their day with their chin too far forward so aren't aware of what a neutral spine all the way up even feels like. Try it in the mirror (or series of mirrors...), it will probably feel really weird.
Wait....What?
I can see how both of those apply. When someone says "tuck" your chin, to me it means retract your head. In the same way a chicken does when it walks. I always do this for heavy squats. Never thought about doing it for deadlifts for some reason. It makes quite a big difference IMO.
No, neutral spine is just better.
This doesn't mean you HAVE to do it, obviously.
OHP, Squats and Deads are pretty taxing for the core. When you say issues, do you mean pain or pump/tiredness?
Sounds like it needs a rest and time to recover. Do you normally do those 3 complexes in one session?
