Default lq9 or not?

Hey guys,
So the motor is coming out of the 98 Z this weekend for heads, cam, intake, and basically a freshening. I have and lq9 short block ready to go and I'm curious as to what everyone thinks. Is it worth leaving the 5.7 out and going for the 6.0? Just wondering if its worth any gains. Heads are absolute speed stage 2 5.3's, 224r cam, ls6 intake, and 42lb injectors if needed. I would appreciate everyone's input as im not sure which one to go with.

i have seen a few guys say that they picked up a 1/10th and 1 mph or so when they switch to a 6.0l you might get a tad more with it being an lq9 instead of a lq4. That cam should be very tame in that setup also.

If it ain't stroked yet I'd leave it out for now and just put it in later once it is

For now i would keep the 5.7 in it, that way you can still drive your car around, while you are building a kick *** engine for it.
