12g's are junk. I tested all of mine before install and you can read about it here https://www.oilburners.net/threads/glow-plugs-6-9.84881/#post-1017290
I put 60g's in mine, and they work well yet. They need cut or ground to fit, so if you want a self limiting plug, bosch 80034 will fit without modification. Can't comment on their reliability. You can read about them here. https://www.oilburners.net/threads/custom-60g-glow-plugs.88914/
Best timing depends on usage/preference, mine in the bus runs best at 6.5°. If you've got a meter, move the timing around and see what it does. I don't think your timing being at 8.5 vs 6 or 9 would cause your issue.
If you're sure you don't have air intrusion, to fix this I'd replace the plugs, followed by injectors, followed by the pump, with testing after every part replacement.
I know they're "new" but if the injectors and pump aren't from a good rebuilder, I wouldn't count on them being quality. I wouldn't consider standard a good rebuilder, nor gb, at least not without checking them myself first.
