I have often wondered if the nikasil cylinders for the VW would help with
the marginal cooling of the heads. My answer, without a shred of empirical
knowledge, is that it would. Back in the 60's my Ducati racer had a copper
gasket between the head and the generously-finned cylinder (aluminum with
cast iron liner). I was told by 'Ducati experts' that the cylinder drew a
lot of heat away from the head.
The nikasil cylinders would certainly cut some weight.. 10 lbs IIRC.
Wonder if ceramic or other engine coatings would help with the head cooling.

Great Plains Aircraft sold the nikasil cylinders for the VW for a few years. They talked about the weight savings and the cooling. They now say that they didn't work out. Never heard the why just that they don't recommend them any more.
