ET Performance Heads
I have a 99 A4. Current mods are Vigilante 3600 TC, Kooks headers, hiflow cats, Z06 exhaust, LS6 intake, Vararam and a 224/228 595/601 114LSA cam. I am also running 3.15 gears. My best time in very good air is a 11.70 @ 114.3 mph with a 1.60 60 foot on drag radials. This 60 foot only happened once. I am generally between 1.65-1.70. In average air I run 11.90's-12.0's and in crappy air 12.2's. My car also dynoed at 366 rwhp. I am thinking of having a set of 215 cc ETP heads installed and retaining the current cam. How much rwhp do you think I will gain and how much ET will I gain? I don't want to install a roll bar and I am worried that I may be going too fast. It is ok if I occasionally dip below 11.50 in very good air, but for the most part I want to run slower than 11.50. What do you guys think? Any other head suggestions. BTW the Vette Doctors will be doing the install so the car will have a good tune. Thanks!

This may help you a little.
Before.
220/224 581 114 cam
Kooks headers
ls6 intake
3.42 gears.
After
AFR 205 heads
Ported TB
3.90 gears.
You might get about 15 more rwhp then me. Bigger cam and better flowing heads you would have.

This is on my '05 C6 Z-51 4L65E:
Just finished the install of ETP 215 58cc heads, Comp 224/228 .581/.588 114 +1, FAST intake and Yank SS3200 converter. LG Pro Longtubes, Corsa's and Halltech Stinger were already installed.
444 RWHP and 414 RWT tuned by Jeremy Formato.(The 360/360 was with the headers, halltech and tune only.)

The Best Heads
THE IDEA is to use the best parts
Go fast parts cost money ,but reliability and power puts a smile on your face.
I would say get the car going fast ,don't worry about the roll bar YET!
I would get the 225 ETP Heads with my set up, and I have an A4 with a smaller cam . 224 /220 581 /566 112 /112 +0 advance
I am now running 5.3 heads .
My best is 11.61 119 1.61 60 (Roll Bar soon)
I figure the car would run low 11's with the new ETP-Performance heads and 10's with a solid roller.
The Gears and drivetrain would be the weak link for me.
Rodney (RPM Transmission ) has built me a A4 transmission from hell ,that is no longer a problem.
USE THE GOOD STUFF.
Have fun
