Another 360 question (or two)

Just got my 360 back from my buddy. There are a few things that I have to do. One is the heater hose and water pump to manifold bypass nipples. What should I use as a thread sealer? Just regular teflon tape?

My buddy also had to extract one of the broken exhaust manifold studs that go into the water passages. I bought some new studs. What should I use to seal that?

I did install the flexplate with the correct loktite and torque spec. Thank you for that.
