with aluminum manifolds and heads always use anty freeze, have witnesed many eaten intakes  frome the southern us wher no atyfreez is  needed.use the proper stuff for longer life,change every 2 years. just my opinion.

any one use this stuff? boat guys maybe. http://www.tefgel.com/contain.php?param=tefgel_inforI use ARP anti seize or, in your situation Arp pipe seal which sounds similar to the Tef-gelstu

Not sure on the electrolysis but I would suggest not using stainless on aluminum unless you use an anti-sieze compound. The stainless will gall the threads in the manifold and not only ruin the threads but make it extremely difficult to remove if need be.

I was not sure and wondering if there would be any problems with electrolysis if I used a plated steel heater hose connection into an aluminum intake manifold?
