injectors directly facing manifold runner floor

Hi, I've made up an injection setup for my old commodore as i was
sick of the carby and i have done a very basic setup with the manifold
but i was after some opinions on wether it's now worth me redoing this
part now that i know everything runs ok.

This is a pic of how it is now

As you can see the injectors face straight towards the floor of the
manifold runners.. it was the easy way to do it because to slope it
towards the valves means i[d have to come up with a custom thermostat
housing and hose and move the air temp sensor and brackets for the
accelerator cable ect... So if it's not too bad i'd like to leave it
how it is but not if it's shockingly bad.
The car runs ok.. quite well actually.. i havn't been able to see
any signs of fuel pooling when runing it and then ripping off the
throttle body.. but who knows.. So any opinions on wether it would
be ok to leave it this way or not ?
cheers

pretty typical.
should run just fine.

on really cold startup, if you compare to another identical engine with injectors pointed differently, you MIGHT be burning 5 percent more fuel when it is very cold for a very short period of time, and it MIGHT idle slightly rougher when very cold.
