<VV> valve seats (Now Engine bay Temp)

[James Davis]

After a hard Interstate run in the Rampside, the rear bumper is too hot 
to touch as is the outside to the tailgate, but the uninsulated engine 
cover is cool to the touch.

This is unlike a conventional vehicle with a grill and radiator that sees high volumes of air movement by virtue of the vehicle's forward motion.  There is surprisingly little air motion along the sides and across the tail panel on the inside of a Corvair engine bay but there is a great deal of radiant heat back there and that is the point of induction air pickup.
