number 6 cylinder
 

How do you cool down the number 6 cylinder

You don't! Maybe an aftermarket manifold! Do you have a pyro in each cylinder? What makes you think your running hot in #6? It's common on these to do that but not to the point of damage

i agree. unless u get a custom intake that covers the entire manifold like alot of the pullers use. i dont think ull see much of a difference.
however i would guess if u got the front 4 cyls cool enough then the back 2 should be atleast decent. like where they say to install your pyro. if u put it after your turbo and its hot. u damn well know ur cyls are wayyyy to hot. best idea. dont run er hard very long
