550's will struggle at that level on a 2.5, I'm doing something very similar with a 2.6 stoker, ive got some 650's to go in it. Give me a shout for a turbo, i'm working with a supplier for a new range, a 400-450 unit is on my test car now and looking good :-)

I ran a 2.5 with an AFP 20g for around 400bhp.

Injector duty was high with 550's, fitted an FPR and it was OK.

The late, great Harvey specced 740's for my build, 400/400. Forged 2.5.

It runs an HS TD05 20g.
Tubular headers and Harvey trick up-pipe.

Don't assume that because your injectors flowed enough that all 550's will flow the same, they can vary alot, ive seen them flow 510 to 570cc. Some may make 400bhp ok but ive had them run out of puff at 380.

Whats the price difference between injectors? Ive heard its not worth messing about and you should just get what you need and then sum,plus will be ready for future mods if you want more at a later date.
