will ls1 headers bolt up to my lq9 and will a t56 bolt up to the moter also. thanks guys

 

Yes. The motors are externally the same.

 

Yeah they should bolt up. Be sure the rear flange on the crank is the same thickness. There are some differences between some .6.0L motors and LS1 motors on that. Other than that, it should be pretty easy to swap everything over.
