Here is a contrasting opinion for you - you'll be fine replacing headbolts with studs 1 at a time. With 9 other bolts torqued up the chances of anything moving are slim.
I also ran a gt2052s at around 27/28psi on an xud. Turbo went on after at similar boost iirc, and had many a mile put on it. No doubt it was slightly out of its efficiency range and on the cusp of shitting itself, but hey ho. Tbf you should be able to get away with far less boost on a hdi for similar powers.
Of course, your milage may vary ...
Best thing you could do it monitor EGT and backpressure - you'd see if you're in the 'danger zone'. Oh and keep a spare turbo in stock.
God bless the internet
