Matching Injectors to Pump
I'm planing on putting on my new heads, intake and cam... all trick flow.....this weekend... and I went with 24lbs injectors.. I figured if I'm going to pull this all apart might as well replace the stocks ones with new injectors.. I got a good deal on em... anyway...
with twisted wedge heads, street heat inatke and stage 1 cam, will I need a new pump... I actulay replaced the pump with a stock replacement when I first got the car, I had to replace the tank cause one of the baffels broke loose.. so when I replaced the tank I replaced the pump.. seemed like the right thing to do at the time. So the pump is fairly new... but with 24 lb injectors and an adj FPR will I be ok with the stock pump? -as

I ran 24lbs injectors on my 190lph fuel pump and never had a problem with fuel flow. I am currently running the same 190 fuel pump on my 30lbs injectors
 IMO: upgrade to a 190 at the very least... |

You'll do fine with a 255... you'll just have more fuel in your return line. That's what it's for, so you'll be fine. You won't run rich because you have a AFPR for that
