Massive disappointment today......I guess I should have read this thread. It appeared to me from the way the website is that these are in stock, should have known better. I'm moving out of state in a few weeks and have a very small window to work with.
Wanted to throw a set on my truck to go with my cam specifically because of the small runners, but will now have to settle for ported factory heads. I bet these would be great for trucks.

Sorry guys, got no dyno numbers. Installed these heads on my LS2 Corvette, that was previously equipped with LS3 heads. Other specs:
Kooks headers, G6XE cam, FAST102, UD pulley, 4.10 gears. Stock mufflers. Idles, drives, sounds like stock. Due to traction issues at the track (no prep) I ha the same speed at 660' 97,19 mph as before, at 1320' I had 123-123,5 mph before, once I got 124. Now all the runs were 126, 126,7 being the best. The car feels wicked fast, I think there's an easy 128-129 in there with decent traction. Not bad for a stock behaving LS2 with a tiny cam.

I ordered 3 sets until now all of them took less than a month to get to me all the way around the world.. 
Made 492rwhp 468rwtq LS3 on Lumina SS (GTO) crappy 1.3/4 headers ORX , stock intake and tb , Big tires , 3.73 gears , G6X3 .
I'm very sure with a better set of headers , Fast intake the car will be over 520rwhp
The other two sets we still didnt install them yet ..
Great work like always TSP.

I had the same problem but with my stroker kit. Web site made it seem like they would be there in 3 to 5 days which was obviously not the case. They should list the wait times accordingly as it is not fair to customers on a schedule.
