I posted this on the GTO forum, and thought I would share here. This is a video of under-hood sound of my Yealla Terra roller rockers. These things are worth their weight in gold. Eventually, I hope to find the other videos I've made of me going through the same drive-through at a local St. Louis Bread Co. for comparison from stock + headers, cam only, and now the L92s with Yella Terras installed. Even stock, I used to be embarrassed at going through drive-throughs. Not anymore. They were a little louder (barely) when first installed, but quieted down after a couple thousand miles.

Nice. Can't even hear you have a cam. I've been contemplating trading in my Z for LS2 GTO and I'm leaning towards your setup. Did you make a 1/4 pass yet with all your mods? What about a dyno? If not, how did it feel after putting the heads on?
