You might want to check out
http://www.faqs.org/faqs/autos/gasoline-faq/part1/index.html
for a little "light" reading on the characteristics of modern gasoline.
Note section 4.10.2 says that vapor lock protection classes start as low as
41C. The highest class is only 60C = 140F, which is still not likely to
cause "serious damage to the rest of the components".
Assuming the problem really is vapor lock, not percolation in the carburetor
bowls (which is very common in older British cars being run on modern
gasoline), one work-around is to put a higher pressure fuel pump near the
fuel tank, and a regulator near the carbs to bring the pressure back down to
the 2-4 psi most LBC carbs like.
