Tips for installing heads.

I'm about ready to install the heads on the block. Any tips, suggestions, and or advice would be great!! The block and heads are mid 70's mainly stock 360 parts. I have read about using #2 Peratex around some of the holes, using thread sealer on the head bolts, and black RTV around the coolant holes. The head gaskets are the Fel-Pro that came in the engine kit.
Thanks,
Mike
