can i install 454 injectors in my 350 throttle body without any other modifications to the computer or other componets. I raised the compresion with flat top pistons ported the heads and exhaust manifolds I used springs with 95# of seat pressure and an engine pro cam with 204-214 at .050 and 420-443 lift part # MC-1730 with a one inch spacer under the throttle body. the engine is in a 95 GMC Youkon. would raising the fuel presure with an after market regulator help?

First i believe you're 350 would be better suited with a performance chip added rather than the bigger injectors.
I'm not for sure but i think the difference in the injectors may be only in the outer diameter. the ecm controls the injector pulse with using many variables collected from the engine control sensors.A performance chip will improve the factory ecm settings including timing,injector pulse with,and transmission shift. An aftermarket regulator may damage the fuel pump since it is a stock part designed to operate at stock pressures. hope this helps some.
