318 Install Question

I am about to install a new 318 in my 70 Dart. I have a hoist and leveler.

Engine and tranny (904) will be installed bolted together.

My question is - where are my best attachment points to the engine for the leveler?

Also, does anyone use silicone or some other sealant for their intake manifold gaskets and head gaskets?

Thanks in advance for your help.
