I'd choose th PRC 2.5's. The Darts would need to be worked over to match the performance.

To be honest, I have not decided..

But from what I hear, I'll probably go with ARP studs..

Right now, I only have the heads and the cam.. I am still working on gathering up the other items..

Yeh, that's just silly..

I dunno, I am a few months from having everything ready to go, so we'll see what I wind up with..

The ARP's sound like the way to go though..

I dont know if your an A4 or 6speed,I'm an A4. When I just had a Tr224/112cam and ls6intake I put down 350rwhp.Then I added TSP stage 2.5 5.3 heads and a ported Fast 90/90 from vengeance.Ron Said that the intake would be good for around 25-27rwhp.well when its all said in done I now put down 417rwhp 407Rwt. So the heads and intake netted me 67rwhp.I say 40 for the heads and 27for the intake.Hope this gives you an Idea.You may gain more on the dyno if your a 6peed

I have not tried the PRC heads, but the Dart 205s gained me 28 rwhp over my stock ls6 heads. The only work I had done to the Darts was some milling to keep compression up.

Numbers in sig.

The Dart 205's gained about 30 HP and 20 FT-LBS over the stock heads. Completely out of the box Darts with GM gaskets.
