Exhaust manifold leak !

Putting things back together is usually reverse of taking apart, with the manifold's should i install both and finger tighten all nuts and then torque them ? Or install exhaust manifold and tighten studs except the 6 that siamese with the intake ? Also i removed the intake heat shield's to make it easier to get to the btm studs, i am guessing i should attach the heat shield's before installing intake ? Starting those bolts would be a pain with the intake installed.

install the heat sheild near last. I am not to that point yet, but it would just get in the way. Besides, its held on by very easy to reach bolts at the base of the carbs. I torqued all the header bolts that were independent of the intake before I put the intake on. Makes for less contorting my body later.

My '77 has fuel injection so those heat shield bolts are a little harder to get to but like you said they just get in the way. I have been trying to clean the years of muck out of the intake runners and throttle body, i have gone thru 4 cans of cleaner. Also i have only one day a week i can work on the car, and it is going to rain this weekend so looks like another week of sitting :disappoin

hm since your intake is an FI manifold I'm not sure the best way to do it. With my gasket and studs ready, I placed my header and intake on the studs. I left my balance tube snug but not tight so it would allow the manifold halves to tighten flat against the head.

I started all the nuts/washers and got them all snug. I torqued everything in stages so I was certain the torque was even. I did not install my heat shield and carbs until I finished torquing the manifold and header.

If your heat shield is anything like mine, it blocks most of your access to the exhaust studs.
