Thanks to all for the overwhelming responses on this topic. I 'have' left the divider there. I just don't see how anyone could think of removing it as a performance gain. If you look into the runners from the heads perspective, a removed divider would have exhaust streams colliding with one another. So last night and this morning all i did was enlarge the hole itself to match the PTE 7cm inlet.

I was gonna enlarge the runners slightly based on a vfaq pictorial but i don't think i'm gonna bother with it. If you hold the gasket up to it, you'd have to remove a ton of material to equal the size of the gasket. I don't think it's a benefit, not for a 50 trim turbo. Some say a 50trim won't outflow the capicity of a 2g head anyway. Heck, Brian(Slowwhite), runs a much bigger turbo that i got on his 2g stock head.
