I run the first gen W-2s on my Challenger T/A. Ryan at Shady Dell modified the heads to accept the stock intake bolt pattern and then oval ported the intake. He has done a few. Oh, by the way, My T/A won 1st place at Garlits in E-Body stock class. the judges never caught it. It also has run 11 second ETs at 116 MPH at over 3500lbs.
I also have a Holley Pro Dominator intake. I threw it on for giggles with the 770 cross ram carbs off my Hemi and it was a rocket. It all fit under the stock T/A hood also. never took that combo to the track.
