Think its time for a cam.
But like you said its all about combination.
The op may want to read this thread as well, it may be a bit older, but has lots of good info.

Stick with 230 and under. The cam I'll likely go with for my DD and possibly a set of 243 heads will be around 228/232. EPS has a nice 222/226 and 226/230 cam thats a great driving cam that makes big numbers. Others can do that too. I've seen cam only cars with over 235 deg duration only make 400whp when some of the smaller mid 220's cams are only 5-10 hp off but make a crap load more power under the curve where it counts. If you go heads down the road, you can make 430-450whp easily with the right smaller cam and supporting bolt ons.
IMO you should do heads/cam at the same time as the cam has to match the heads and setup the pushrods and valvesprings on the 5.3 heads you get for the cam you use. No sense in using pushrods/springs in stock heads and then swapping over to different heads and having to get new pushrods and swap over springs.
EDIT: Thread posted above is exactly the reason. Keep dynamic/cranking compression high and you will make good power all over the curve.

If I were to have to do it all over again, I would have gone with an MS4.
The things you NEED to replace are; pushrods, springs, and the cam obviously. Everything else is optional. But it's good to replace things while you're there... like the timing chain, and oil pump...
I have some surging now, but thats because I have a 408 with 799 heads with the same intake/exhaust (read: choked motor) and we didn't spend near as much time tuning because it will change again and again and again as I change the intake, heads, exhaust, FI, etc.
With that being said, a donkey dick cam isn't for everyone and that's not what I am advocating. I am definitely not one to recommend a cam but will point out the fallacy that all big cams surge.

It being an A4 doesn't make a difference, there are plenty A4 TRex cars out there.

You also have to count all his other mods to get him to his 490 range.
I just think its funny.....Your trying to prove me wrong when, I'm not the one saying this the people that made the cam are saying this.
I'm not saying this cam is **** or anything I'm just saying ....if he wants to do heads/cam there are better cams that TR makes to get him the best bang for his buck.
If you want to call TR and have this talk with them have at it .. I'm done...
You might want to show TR that guys car so they can put him down as a point to prove what your saying.

There is no right or wrong in choosing a cam as everyone has different standards. To say that a TRex won't benefit from a fast, better heads, or bigger headers is ignorant.
