Father-Son 1974 Duster Project

Bob it's time to install your exhaust manifolds. :)
I just received the hardware for them Al.
What do you think I should use on the studs? Some guys say pipe dope, some say locktite. Going to have TTI make me the downpipes to the Jegs exhaust kit. Where can I get the flanges for the pipes to mate to the manifolds?
