I'm interested as well. Make sure you get the right valve guides to use your stock rockers. The bronze ones won't work I'm told.

I think they are great heads for the money. I put these heads on with Tick's SNS stage 2 cam in my 02 ls1 and I put down 445rwhp and 410rwtq on a dynojet in 90 degree weather.

It was through a manual trans. I believe the cam specs on SNS stage 2 are 227/235 .614 /.621

Those heads are a great bang for the buck as far as aftermarket castings go! Unstable Vic, you're a little misinformed. For most companies you would be correct but with the quality of bronze that we use in those heads you can still run stock rocker arms with the bronze valve guides.

Really? Interesting. I thought bronze was bronze. Powder metal I thought was what is needed to run stock rockers and not a roller rocker. That was the issue with the trick flow heads right?
