Default 331 injectors!

Hey all,
I've been in the process of making my 331 stroker for about 2 weeks now and I was told that it would be a good idea to put some better flowing after market injectors in. I've found a guy selling his setup... 30lb injectors and a Walbro 190lph fuel pump. Is this pump good for these injectors? Also, do I need to get a new MAF for the new injector size?

Oh, and for your info My car is a 94 gt and the 331 stroker will have the stock heads for awhile! they'll be ported but restrictive!

Also, in case this guy doesn't have his injectors and setup anymore... can you guys suggest a set of injectors to get and the best fuel pump to get along with it!

THanks for the help guys!

do not waste the money porting the stock heads with a stroker. if you have to use the stock heads then so be it, just keep saving for the better after market ones.

trust me i have made this mistake from personal experience
ported e7's with 1.85 1.6 valves milled etc etc

ya... If there was any way I could get the some better flowing heads I would... The engine build is costing way to much for me as it is! lol this guy is not counting the port work in the bill! so once I pay that off I'm gunna get some aluminum heads! one step at a time i guess

Any answer for the Injector and fuel pump question I had? It's semi-urgent cuz the build will be progressing quickly now... We received all the parts today!

i would get some 30's and a 255 pump if its in the budget. the 30's will be more than enough and then down the road if you want nitrous. when the car is tuned they can correct the injectors where the car isnt as rich

ok cool... do you have suggestions on where to purchase the fuel pump and injectors? I tried americanmuscle and they didn't have the fuel pump. Also, do I need a calibrated MAF... or can I put a fuel pressure regulator on?
