fuel pressure to much or doesn't matter I currently have 60 lb injectors on my 408 stroker. I switched over to a adjustable pressure regulator but I was wondering....my gauge in the car says 60 lbs but coming out of my fuel rail the pressure is like 67 lbs. Will this make my injectors flow OK or will it cause them to now flow good? Just didn't know if a bit more would hurt anything since they only flow 60 lbs or it doesn't matter cause it won't make them flow more.

Your injectors are probably rated 60lb at 3-bar (43.5 psi) meaning you are flowing ~73lb at 4-bar(58psi). The extra pressure causes them to flow more but as long as you have the correct data entered into the IFR table (based on your fuel pressure) and you re-tune your VE everything will work out fine.
