HAS ANYONE MESSED WITH THE INJECTOR HEIGHT TO CHANGE SPRAY ANGLES, AND IF SO WHAT WERE YOUR FINDINGS, SHOULD I JUST GO WITH THE FACTORY SETTING, MY NEW CYLINDER HEAD IS HERE AND READY FOR ASSEMBLY, HOPING TO HAVE IT SMOKING ON THURSDAY NIGHT... , THE INJECTORS I AM INSTALLING ARE FROM INDUSTRIAL INJECTION, THEY ARE THE 3-FLOWS AND I HAVE THEM BACKED UP WITH A STAGE 2 DUAL FEED SET UP AND EXTRUDE HONED CONNECTOR TUBES, AS FOR THE HEAD GASKET IS THE FACTORY MLS STYLE SMASHED WITH ARP 12MM STUDS, I WANT TO RUN 75-85 PSI FROM THE TWINS, WHAT ARE YOU GUYS TORQUING THE STUD NUTS TO???? ANY TIPS OR INFO WOULD BE GREATLY APRECIATED, JUST A NOTE IT WILL HAVE A STAGE TWO SNOW ON IT AS WELL...

Me personally, I would leave the injector installed height alone. I would think that it is critical on these engines with the high pressure cross over tubes. If you were to raise it, the tube might not align properly with the socket and leak under the higher pressures that we experience on these engines.



As for the head studs, ditton on what Justn said. It has held all I have thrown at it.

THough it was not by changing injector height, My spray angle is not factory. It was done while making the tip.



And I think it helped quite a bit... Not so much though on 04. 5+ truck (so I hear)
