I have a 99 2wd extended cab Silverado,4,500 lb's.With a 2005 LQ9 6.0 engine,longtubes,compcam 208/212 dur,554/558 lift,and occasional 150hp nos shot,built tranny stock torque converter,it runs 13.7 at 102mph NA,and 12.4 at 112mph on 150 shot,getting ready to install a 3,200 Yank stall,keep in mind i use this truck to haul my car to the track,Would some L92 heads be to much flow or even right for my setup,may need to go bigger cam also if needed,on stock cube 6.0,with 4,500 pounds ??? Any help Thanks

They have potential to make some really great power without huge camshafts or sacrificing your street manners! Since your LQ9 is a flat-top piston, you could get some decent compression out of them with a little milling. Stock L92's paired with our 225/230 camshaft have proven a very good combo thus far!

best intake hmmm how about a 102mm lsxr FAST intake
BUT if the cost it so much then go with the l76, BUT get it ported, or stick with the truck intake which is still not a bad intake They have potential to make some really great power without huge camshafts or sacrificing your street manners!
