I got this comparison, same car, same dyno. I think this dyno is hard on cars to be honest, as many people go away disappointed, but just use it as a tuning tool the facility is spot on.
Low curve= 383, 224 cam, LS2 intake, NW TB, flowed 853 heads. Comp roller 1.85 rockers. ( with valve float i now reckon! )
Mid Curve= 416, 233/237 cam, ported LS2 intake, Worked Dart 225's. Std Rockers
High Curve= 416 244/257 cam, ported Fast, same Worked Dart 225's, Std Rockers.
Mid Curve gave me a terminal of 128.7mph, i am hoping that i can break 130mph with the new power! We did see a 513/510 run once but the curve is short.

I have worked on the Darts, as in i've opened up the chambers to match the bore, aswell as some blending and smoothing, but i'm not sure that nigh on $3000 dollars might be worth 20rwhp?? (by the time i ship to the UK that is). I also am kinda stuck with my exhaust because of room, But they might be the reason for the big torque.

That car should fly. My friend had a 416ci setup with TFS 235's, ported FAST 90/90, small 236/236 115LSA .600" lift cam (or that's what he told me), 1 7/8" long tube headers, into a dual 3" then single 3.5" system with 3.5" cat. It made 540rwhp/510rwtq. Redline was 6800rpm.
The TFS heads will make a little more power I believe; however unless you are already driving your car to 95% of its potential it would be a waste of money and time. You are running a very healthy cam. If you need more power simply spray a 100hp nitrous shot.

and i've seen some big #s from properly worked Dart 225s...
there's several builders out there that think the Darts are one of the best heads when properly set up...

how big are your headers?no matter what heads you run,your exhaust is going to hold you back if it's not big enough to support the rest of the engine mods..

Car drives fantastic, like a ***** cat down below, can drive at 1200rpm with no kangarooing. It just builds and then smokes the tyres 
I've included an idle clip, got to hand it to the tuner and the time we spent in the 1200-2000rpm range on the low load sites. It actually drives the best so far with any cam!
