Oil cooling is another viable option, but again, your oil does 2 things here. Lubricate and cool, it need not be much special that conventional high grade engine oils but the system pathways and maintaining a clear oil throughout the system is a headache. Plus not to mention a special spray lubrication in engine for better lubrication as oil is circulated throughout the system and radiator, which also requires a bigger sump pump.
Air cooling is cheapest of all option, just put the liner in aluminium alloy fins and you are done. No sump pump, no extra coolant, no radiator (so more space) and even no spray lubrication. But the downside is, if your engine is producing a lot of power, for the displacement, it will be dealing with lots of heat transfer and losses and wont have enough area to actually dissipate the heat even with those fins, thus the engine would run a lot hotter. Probably won’t burst out, but would wear a lot faster and would operate way out of its efficient rpm range
