VIN information
Also wanted to know where to look on the heads to tell what cast they are without taking them off the car.
Finally wanted to know if there is a way to tell if I have an LS6 intake without taking it off and looking under the bottom.
Thanks in advance. I hope this is the right section.
Look on the passenger side head at the lower front, the casting number will be there. See the pic below. And for the intake, there will be a part number on the driver's side in the middle.
