5 and 2

Number 5 was actually the one throwin the misfire code....but number 2 was CLOSE behind. All of the exhause valves were turning white like they were overheating. Number 5 got to the point that it lost it's seal. The seats look great. Thank goodness. Also, the margins on the exhaust valves are VERY thin. I think that probably didn't help. What I think did it......the fuel was stopped slam up. Before I tore it down, it also had a PO171 lean code in it. Plus, number 5 injector was crudded up.

Now for some opinions. Without goin into detail, my exhaust is modified. In other words, it flows REAL free. Get me? Plus, it has a 3" cat back all the way to the bumper. The stock injectors are three hole squirters rated at 13.5 LBS per hour. The next step up and also lister to fit the truck are some 22 LBS per hour four hole injectors. With the exhause freed up and my MSD coil, NGK wires and plugs, yall think 22 LB injectors are over kill? I'm, GONNA get new ones anyway, cause I aint doint all this a THIRD time. LOL This is gonna be expensive right when we don't need it too. Head gasket set, head bolts, new valves and injectors. I am just thankful to GOD tat I can do all of the work myself....even if it takes my disabled *** ten times longer to do it. lol So what do yall think? I know nothing about fuel injection.
