Father-Son 1974 Duster Project

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?

When TTI makes the headpipe tell them which manifolds you have and he'll put the flange on for you. I think I used an antisieze or a hi temp rtv where it goes through the water jacket.
I think factory spec is 30-35 but I have never tightened them that far 15 then 20-25 pounds on those fasteners, no need to kill them. Also torque from the inside out.
