g5x3 vs g5x4
You cant go wrong with either. Get the X3 on a 112 or get some ***** and go with the X4 on a 111. You are not going to have to flycut with either of them on stock heads. You can even pick up a set of unmilled LS6 heads, bump your compression .5 point and gain an additional 15-20hp.

G5X4 with stock LS6 heads....a pretty nasty setup for not so nasty of a price. I don't knwo what to expect in terms of dyno numbers, but I know Z06's have put down 450-ish rwhp with the same thing. Given that I have an A4 with a stall and gear, and I'm going to get it tuned on a Mustang dyno....I'm still hoping to get over 400rwhp.

If you worried about reving it, swap out the rod bolts.
My motor has 41K miles and has always been pampered...oil changes with nothing but synthetic oil every 2K miles. I'm running stock lifters after I pulled them all out and checked them very carefully. Stock rod bolts too...I have an A4 street car, not looking to rev as high as possible.
