UpdateApparently, this is the engine from one of Petermax Müller's custom hotrods.
From a thread on the Samba:
"Petermax Müller was born near Berlin and start his buisness at the Brennabor car factory in Brandenburg. In the 1930s, he sold cars of the Auto-Union. He was also a famous international racing driver. At the end of war, he left Berlin and started his new life in Velpke near Wolfsburg. He was in a good contact to Volkswagen to get the parts. The body of the racing-cars were made by a small bodywork comany im Wolfsburg named Schwon. The Petermax / Petromax (VARTA)-racers were the best cars in its class at the late 1940s. One of the drivers was his friend from good old times Fritz Huschke von Hanstein - he is the guy who growed up Porsche from a small manufatory to lhe world legendary Sportsmark.
In the 1950s, Petermax opend a dealership for Volkswagen and Porsche in Hannover, well known in Hannover area.
In 2002, Petermax died with an age of 90 years. His private car collection which was in display of the Volkswagen Automuseum was sold and I had the luck to buy his Hebmüller Convertible. His VW- and Porscheshops still exist, but they belongs to a consortium of several VW-shops in and ouz Hannover."

I had forgotten that Ultra VW Magazine did a full feature of this car in their September 2007 issue. An internal shot of the heads:
Check out how long the rocker arms are!
