The late R.S. "Bob" Hoover was working on a project to develop a VW-based standard, affordable homebuilt aircraft engine, basically a big bore VW with low-cost accessories and mods for better performance.
A key element of Hoover's approach was the "fat fin mod" which involved brazing or welding on additional fin area to allow the VW heads to shed more heat.
I came across these ready-made "fat fin" VW heads and there many be others as well. My question is, why aren't all the large VW conversions using these or something similar?
