1. What gasket should I use? Erling? Victor Reinz? What is OEM?
2. Would copper spray hurt, help, or really not needed. I have read different opinions.
3. I know the torque specs for the intake nuts are elusive or even non existent but, people must be tightening them to some value? What should I tighten the nuts to?
4. Is it a good idea to replace the manifold studs and nuts or really not necessary?

I actually reused My Manifold Gasket by Spraying it down with Copper-Kote. So I know it is not going to hurt. I figured the Glue would burn off and the little Copper particles would squash and seal. But, that likely makes me a Heretic.
If I remember correctly you cannot get a torque Wrench all of them any way.
More importantly I found that My Exhaust Manifold was slightly warped and I fixed that.
You need to be carful on the Torque of the Manfold Nuts becasue the Studs that go into the Head only have about 4 Full threads on them. I know because 2 Studs backed out when I was trying to remove the Nuts.
I found a torque for all Copper Nuts that thread size at some internet Hot Rod type seller and then lost it and can't remember the site. But, the solid Copper Nuts are supposed to prevent over tightening.
