if you want to get the aluminum off get some muriatic acid and soak the crank journal in it. it'll eat it off . the acid is only like $10 or $15. use in a well ventilated area and keep a bucket of water near to neutralize it in case of a spill. We use that method allot to get aluminum off of the bore's with the pulling engines We build.
We've been putting an insert in kohler rods for close to 30 years. while you can use the 16 rod for this I have seen them fail. like I said earlier the rod is a weak link, if you get the Alcoa rod out of the K361 and insert that. that makes a real nice setup. doing either does affect engine balance and you should probably it balanced for long term reliability.
