injector problems

I okay I have k20a2 into a EG I swaped and I am boosting. I have a set of venom 660cc injectors left from my last setup. These were dsm injectors I used on my h22 worked fine etc... I go to put them on my fuel rail they are rather bulky and they fit very tight at the bottom on the intake manifold...should i just cut like paper thin bushings to seal the bottom. For the top on the rail they were super loose so i took the seals from the tops of the oem injectors and it made a decent seal. Just wondering if anyone has had experience with swapn injectors like this. Thanks
