Does installing a custom manifold increase the risk of overheating engine parts?

I was just wondering if I were to install this manifold: http://www.kinetixracing.com/new-ssvextremeflowkinetixmanifold350zg3503-06.aspx if it would increase the risk of overheating any of the engine parts, please take into consideration that I have already installed an injen cold air intake system, and a performance chip. Also does the manifold violate any stock warranties?

Thanks in advance for any reply! :D
