I think I will be happy with these heads, they have 2.02/ 1.60 valves and the springs are rated to .625 lift so they sould work out good with the cam.

 

yes they should. from what i've heard, its PRETTY hard to over-valve an LS1, the only problems are getting big ones to fit, and not having ptv issues. Plus i figured the increased exhaust flow on the head would help compensate for the slp dual/dual that i'm sticking with.

 

oh...don't get me wrong...the Dart 205s will be an awesome head for that combo. should help make some killer low/mid range power.

they are the heads i'm planning on running on my 233 cam (someday )
