I believe the height of you engine is critical for everything to fit right too. I used the clamshell mounts which raise the

BTW, have you checked into the LS-1 site or trailblazer ss site? there are guys that will sell manifolds cheap on there
when they upgrade to headers.
Good luck
I am using the clam mounts also, they bolt directly to the perch from performance online. I think if the engine sat a half inch lower the LS2 exhaust manifolds I bought would have fit. I did not look on any forums, only ebay and craigslist. I went ahead and ordered the hookers with ceramic coating.
