These work great for me. 1969 Chevelle
I was a little concerned since the reviews (2 @ the time of writing this) were a little vague. However I installed these last night (in about an hour, including removing old headers) and they fit perfect. 1969 Chevelle with original frame. LS3 from 2013 Camaro SS. TR6060 6-speed manual transmission. I have not connect them to the exhaust system yet, but I'm sure it will be just fine.

Warped flange
They look amazing for the money! but to good to be true. #7 cylinder is warped about .060 either sending them back or pay to have them machined flat. UPDATE: I emailed Speed Engineering and they said as long as I use OEM GM gaskets 12617944 I'll be fine.

Three Stars
Had to dent 3 places to get them to fit. The rest was good
K**.
lines up great with my existing flow master exhaust
No room to screw the O2 sensors in, will not clear the floor pan at this point, other wise, a prefect fit, lines up great with my existing flow master exhaust system
B**
Plug wire fitment
The only issue I had was a couple spark plug wires touched the header tubes.
