Thank you newdude! Thanks for looking this up.

Hello All, I plan to replace my driver's side exhaust manifold. The bolt closest to the firewall is missing. Cylindre number 7. I plan to replace it with a new GM Genuine manifold. New steel bolts (not stainless). And new gaskets (GM Genuine). What is the difference between these two manifolds? Is the higher priced part (with a larger part number) an updated/improved part? I see that the cheaper part is made in China. I have no problem paying more for the better part (possibly made in the USA) but I can't find any information as to what the difference could be between both parts. This is for my 2011 Chevrolet Suburban 2500 LS. 6.0L L96 engine. About 52,000km ~ 32,000 miles Thank you!
