How would LS2 heads on an LS6 work? I was curious to see if this would yield any gains...they're the same casting, but the LS2's valves are unshrouded.
Anybody have any thought on this?

...LS2 heads are 243 castings....also known as LS6 heads so np gains there. I believe the unshrouding is due to the larger bore of the LS2
Bryan are you refering to the heads off the new Z06?

I know it's the same casting, but they're modified...thus the unshrouding. GM uses that casting for many head applications and then modifies them (ported, valve and spring change,etc.)
It's not that I'm trying to run out and buy a pair, but I was curious as to what, if any gains could be expected over standard LS6 heads.
Besides, if you're going to use those ported heads, you're going to have to start looking at some more aggressive cams to take advantage of it...GM's cams aren't the greatest from what I've heard.

One of the CF sponsors pulled the LS2 heads and verified they are IDENTICLE. The CC is not modified at all to take advantage of the 4.000" bore versus the 3.90" bore(may be a bit of power on the table for LS2 owners).
The LS7 information is well know. It has a large 2.2" titanium intake valve and a 1.62"(I think) sodium filled exhaust valave. That equals two valves, not 3.

So then what accomplishes the unshrouding of the valves?
