Are they all Denso plug configuration instead of USCAR? Am I understanding correctly that I'll need to not only change the plug ends on the injector harness, but also clearance the Denso plug ends so they won't hit the aluminum edge of the head? I don't see any other way around it. For what it's worth, I'm running a KB3.6 but I don't think it matters since it's hitting the head. Please share your experience if you've done these.... Thanks in advance!
