Gosh guys - I can't remember the valve covers, probably last saw them in 
1969.  I kind'a remember the engines being 409s,  since that was also on of 
the hot rod setups of the day.  Could have been easily something else 
though - that was about 41 years ago.
I remember more about the 6 cylinder "Climax" engine that powered the rotary 
snowthrower mounted on an Oshkosh 4 WD truck.  That had split heads and two 
carbs, you could pull it down to about 200 RPM in heavy snow - at least that 
what it sounded like.
