Torch on Aluminum manifold? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

i'd just clamp the vicegrips on it and wack it good with a hammer to see if i could loosen it up// the threads may be history because the dissimilar metals so in the end you might have to tap for the next size plug// you can also drill out the center then tap a bolt in the hole and use a welder to weld the bolt to the pipeplug ,that would bring the most heat to the thread area maybe dislodging the corrosion

Don't heat it! I had an e-brock manifold with a stuck plug in the same place. I took the propane torch to it and the manifold became brittle and broke at the plug. Hate to admit my mistake, but don't make the same mistake I did.
