I think that TH and I are on the same page here. I cut mine to aim directly at the back of the valve ... just like the stock setup because I'm retaining the use of the stock injectors. I guess the better question here is who is aiming at the center and using the stock injectors? If you are, you may not be helping at all and may be hurting your fueling atomization. Now, if you have and you are using the oval port injectors, you are accomplishing what you thought you would when you cut the heads. The key variable here and what Terry is pointing out is that the injector spray pattern is different in the two heads and most people that use the oval port heads and retain the split port injector location reuse their split port injectors.

Naaa, The real question is: Who the hell has gone through the trouble to change the injector mounting boss angle in the LIM (not the head) and fuel rail feed nozzle angle enough to allow the injector to be "AIMED" anywhere at all?
None, nada, no one who's gone public anyways.
So who the heck cares? THe purpose of widening out the valley/channel where the injector spray comes out into the head is to give it the best shot possible for fuel to hit the second valve inlet, irregardless of any other issues. If there's metal in the way then the chance of getting fuel to the second valve is low. So use what you've got and hope you get enough over there. If you don't, no worries because it won't be acting any worse than the stock split port system does, which is pretty darn good anyways right????
