It's factory. All the heads were aluminum and blocks cast iron on the Kohlers except the twins maybe? I think I have some literature somewhere that says blocks went to aluminum with cast sleeves somewhere in the 80's on the series after the x82s in 1986. That info is all from memory but a cast iron block with aluminum head is correct that you have.

Carbon wasn't uncommon. I think there's even a service interval on taking the head off and cleaning. Rebuild kits for a K301 are found about anywhere from cheap kits on ebay, Stens has decent aftermarket kits, or if you plan to use it a lot I recommend spending the extra money and getting OEM Kohler parts. You should be able to get gaskets, valves, rings and piston, connecting rod, governor gear... however far you want to take it.
