could the stage 3 setup fuel injectors handle a p/p head with cams or would it go lean?

 

i have an aem wideband sensor and im still getting familiar with it..this is my first big horsepower car...
my a/f's are never steady...you guys talk about running 11.5's... but my a/f's are different almost everytime i drive the car.. sometimes they're hanging around 10-11 sometimes 11-12 and sometimes even in the 12's... and this is while im idle, when im driving forget it, i dont have the slightest clue on how to read this gauge!!!

now, i know someone is gonna have to talk **** about me buying a car with an extreme list of mods and lots of power, so dont waste your time, i dont care what you think... i love cars, i love power, and i love going fast.. i dont know much yet, but im trying to learn as much as i can because, although im not highly educated and i dont fully understand how the engine works, this is what i live for and, hey, you gotta start somewhere!

anyway, my babies in the shop now getting an engine swap..im guessing those wack a/f's may have had something to do with the head gasket, and everything else, gettting ****ed.. i just hope the warranty i have from my credit union covers the new engine...they payed for the input shaft, but im worried that they're gonna wanna see the car before paying a few grand for a new engine, and once they see whats under the hood i can say peace-out to my warranty!

 

No offense but im a ***** when it comes to my car warrantee like that, imma stick to the mopar rather then have the dealer nod their heads and go im sorry but look at this your warrantee is void. othe than slappin on some mopar stage2 action then when its time to go to the dealer back off with the mopar then throw on the stock parts and when i get back to the crib put all the good stuff back on.
