I heard it was about 800-600 at the manifold and then about 500-400 throughout. Those numbers seem a bit high though. I would think towards the tailend of things the exhaust would have dissipated heat a little quicker then that. Not sure about the manifolds isn't the combustion chamber at like 1200 degrees F or higher?
