Trouble seating injectors after pulling intake

So I spent 12 hours today replacing the valley pan gasket. This was by far one of the most tedious car repairs I’ve ever carried out, mostly due to the immense amount of cleaning required, but also BC I broke one of the small vacuum hoses, and damaged an injector clip.

Got everything torqued down with a proper torque wrench, connected hose, etc, but the car runs like sh*t.

I had a really tough time re-seating the fuel rail and injectors. No matter how much I pressed down on the fuel rail the injectors didn’t seem to really seat in their bores.

Is there a technique to persuade them in? Thank you.
