Reducing engine bay temperatures and improving air distribution, part 1

Thanks to a very observant Timothy Beradelli (fellow 356 list member and seasoned builder), it was pointed out to me that on cars with european heaters (356's that is), in place of the stale air flapper boxes, there is sheet metal that routes the air past the exhaust ports and further downward. 

In an attempt to simulate these missing pieces of engine tin, I fabricated them myself with aluminum sheet, some aluminum angle stock, and lots of rivets. The engine tin is then held in place with safety wire for easy installation (and removal for further cooling testing).
