360 Head replacement

Hey guys, I have some head replacement questions.
I posted a few weeks ago about the header studs on my 84 Ram Charger 360 being all messed up.

I got a set of heads from a 74 360, took them to the machine shop and had them gone through, spring replaced, new seats, they had to weld one up etc.

I havent rebuilt or done a head job for 10 yrs or so, i have a couple of questions.

Whats the best sealer these days for the head gasket?

I dont remember if there is any special set up for the rocker assy.

I have looked at a few different sites and they all have different torque specs for the head bolts, what is the correct range?

Is there anything special i need to be aware of?
