LS6 intake casting numbers

[skeeters65]

Just wondering if any one has the casting numbers for a LS6 intake..

Just trying to comfirm my intake..

Thanks

Never mind I found it
12573572 is a LS6 intake if anyone else is looking

mine is 12573572.
Alternatively the ls6 has a flat bottom and ls1 curved bottom

Also another trick if it is off the car is the bottom of the LS6 is flat whereas an LS1 has a hump down the middle.
