ok I will go out on a limb here and roll a few conservative eyes. (No it's not about "bernie"! lol)
Each head has four large pushrod tubes for drainage. I am not familiar with VW oil flows and maybe someone will say for whatever reason, they wont carry a lot of extra oil out of the heads and it will pool under the covers and seep out everywhere. but assuming they can handle extra oil, I suggested a high vol oil pump and tap an oil galley somewhere with a tee, send the oil to the heads and make sure it flows onto the warmest area. An oil cooler would also be part of the mix. As far as liquid cooled heads are "cooled internally", think about it, the coolant is on one side of a casting with the other being the combustion heat. With air cooled heads its a single wall so the oil would also be running across the outside of a single wall. I just wonder if pumping more oil and diverting th extra flow to the heads would transfer enough heat to make a difference. Especially on a turbo charged engine. Although now Revmaster appears to be introducing a turbo engine turnkey. I'd love to (in a couple years if and when my plane is complete) move the normalizing turbo from the rear to the bottom and bolt that onto a KR1. Imagine the cruise speed at 10k?

But where are you going to get the oil from? The liquid cooled heads are cooled from within. To pump a lot of oil into the rocker covers could cause problems. Plus all that oil.has to get back into the crank case. Oil provides 30 to 40 percent of engine cooling by drawing heat away from components. That heat is then shead while in the oil pan. Control temperature of the oil first. Oil breaks down fast the hotter it gets.Engine baffling is very important. Stop and think about it. A lot of VW engines have been out flying with no problems over the years. ENGINE/POWER MANAGEMENT. One of the first things you learn when flying big engines.
