I dream about owning a set of these heads one day! I have yet to see a bad review about them. Nothing but high marks! I think I would like to have these heads with an xr265 cam (or similar) for my combo. It should wake my truck up pretty good!

I did get these installed, I dyno'd right after and put down 394 rwhp and 365 rwtq. It was on a Dyno jet. My tuner had some issues with my tune in some areas. Like the converter would lock as soon as I hit 3rd, so it would drop to 3700 rpm. It literally felt like it would fall on it's face. I went 13.6 with it doing that. Now I'm still figuring out the tune, my tuner pretty much did his own thing and no one can figure out what he has done. My comanded afr at idle was 10.45 and my wideband was at 14.7. And that is just some of it. But as far as heads go, I picked up 30 rwhp from them. I paid $700 and I love them
