Read in the book "How to rebuild your Volkswagen air cooled engine" by Tom Wilson that silicone based gasket compound shall NOT be used. I had previously bought the engine compound at Würth, but it is silicone based.

Then I found Würth also has another special gasket compound for engines (motor sealant). It is really strange, more like some odd glue, and red. Smells odd too. Permatex aviation "make a gasket" stuff is nowhere to be found here, and it is "hazard" in shipping, so it's out of the question. This red Würth stuff seems right though (according to the TDS, and used by Rolls Royce for what it's worth), but time will tell.
Update: Skruvat, the largest online auto store here have Permatex Aviation form-a-gasket No.3 Not only do they have it, they list it as a bestseller. Sometimes ...... ##¤¤%&&¤  Well, better order.

Put on the red gasket stuff, mated the halves and torqued according to the Aerovee manual.

Looked good, and the shaft rotates freely. However, when standing for 15-30 min it becomes a bit stuck. The same happens when moving back and forth 1-2 degrees repeatedly. To me it seems a bit to tight, but I will weight and hear what Sonex has to say.

Started with the cyinders and managed to break one piston ring. New ones ordered. Painted the cylinders black (thin cote of "barbecue black"). The cylinders will hopefully heat up enough to cure properly.
