Torque spec for Crossover to Headers?

[V6Turbo]

Hi Folks,

Just installed the new header. What is the torque for the crossover to the Headers.

Also, what creates the egg shape deformity of the crossover pipe ends. I'm afraid to overtighten.

Thanks in advance.

Snug it until it does not leak, I don't have a number, but with normal length 3/8 drive ratchet does not take a lot of force . Use anti-seize on the bolts. When everything is new and round does not take much. The fact that the clamp does not apply uniform pressure combined with heat and pressure over time it will egg shape. You can typically hear a leak.
