Did you check the RATE OF galvanic corrosion? You will be dead 5 times over before it "might" be a concern. (Like in aircraft.) VW & Vega & Asian cars & motorcycles (& others) use aluminum and steel interchangeably, Like it is not a Concern even if you have the machine for +40 years.

@1djbecker Really? You worry about the next owner? He bought it. It is HIS PROBLEM.

@MrMasahhh That's easy. The bolt hole that strips is on the outer edge(of course) where no meat can be added as the piece is a certain size...to fit into a certain size location. Sometimes it is "JUST THAT WAY." Such as on aluminum oil pans. A small square of steel is inserted in the factory under 40,000lbs pressure(lets just say "A Lot of pressure" and the part fit is that tight that oil does not leak past. The insert May be no larger than the copper washer that goes between the steel oil plug and the engine. Copper is reusable, rubber gaskets use only once.(sometimes the washer metal is aluminum(which is also soft & found on Asian cars/motorcycles...is also reusable. Choice is used the product or buy a new oil pan (or engine) One is cheaper. If it is an oil plug, usually they "you" cross threaded them in instead of starting it by hand and screw it all the way down by hand BEFORE USING A TOOL. The chemical ones are certainly good enough for an oil drain plug...those that have some resistance. No need to reef on it to break the 5/8" bolt. . If it is a head bolt ? I would question the strength of that but on a gas car it is probably no more than 150pounds of torque(on average)or an exhaust bolt (35lbs of torque) into the head then you want to helicoil it. Price out the cost of a new head. <You will go heli coil insert and have a machine shop do it>.
