My point is, there is the 6.0 truck heads that everyone calls "6.0 heads". And there's also the 243 castings, which came on the LS2, which is a 6.0. Correct? That's why I asked. I see you must mean truck heads. At 72cc, the best you'll have with .030" milling is the stock 66cc chamber size.

241 Castings are F-body LS1 heads, which did start at 66.xx cc. Milling those .030 is just what was needed.
N4cer is right:
6.0L heads are generally truck heads (315 casting) with 72cc chambers
LS6 or LS2 heads are 243 castings and have 64cc chambers
LS1 heads are usually 241 or 853 castings
As for your cam choice, it's alot for a 3200 stall. Your gears will help, but that cam would work better either 4 degrees advanced or with a 4000+ stall (or both). Also, raising the rev limit to 6800+ to work around that cam's Valve Events will eventually take its toll on your A4. Be prepared for a rebuild.
Is this strictly a track car? I'd run less on the street with and auto, but I like my torque. If you look at all of Cartek's grinds (that have duration and LSA #'s) they all have 114 or 113 LSA. I'd consider a smaller grind with a tighter LSA, like the 224/228 110 that has become popular. The overlap is less than the 234/244 cam, and it will pull hard from 2000 - 6500, while working well with your 3200 stall.

Ok im new at this so some help is great. My trans is been built by http://www.performabuiltautomatics.com/ level 3. and my Vert ill have restalled to 38-4k. cam would work better either 4 degrees advanced why is that. what is that doing for me?? what would happen if i did not?? Already have 6600 rpm set. so i can do 6800. no car is not a track car. Will see the track once a month. I had the 224/228 before and loved it. But i want more now, so i got the heads and pistons now. With a 114 will that not give me a better idle. what power band am i looking for and how much hp will i see with this setup. thanks

The +4 will move the powerband a little lower in the RPM range, and give you a more usable powerband. Same for the 114. Better idle, but poor low end, as a general rule of thumb. There are rare exceptions, but your setup doesn't look like one of them.
You got heads and pistons? I must've missed where you mentioned your rebuilt motor.
Also, 6600 is nice. Just remember that 4L60e trannys die from RPMs. I've never heard of a low RPM failure on one.

I just know nothing about the cam, but if you feel it gives you the DCR and rev range you want, then I see no problems. If you didn't have an auto, surely you'd be at 410-420 or more. Not trying to low ball you, but I think most people on the 'net exaggerate their numbers.
