Pretty much what it says....An LS6 ex. manifold will bolt up to a 5.3/6.0L correct?

 

It should. But I'd guess it won't meet your flange correctly, requiring welding. In that case, you might as well step up to some ceramic coated shorties that will directly bolt in. But, if you are willing to spend that much money, go ahead and buy some long tubes.

 

Yeah, no need for them to bolt up to existing flange. Have a project in the works. Whooooosh! Thank you
