Bobby,
I also have the 3300 in a 601xl. After several adjustments with the air
dams I placed a small scoop on the upper intake of cylinders 2,4,6 which
evened everything out, but would still get too high in high power climb.
I then extended the flange lip on the bottom of the cowl about an inch
and 1/2 by riveting a piece of aluminum .o25. Never have any problems
now. Attached is picture.

All,
i have the 3300 in a 601 XL. it has the original low Ram Air Ducts with
the plug
wires going thru the duct at the plugs. i have glassed in the dams
between the
plugs and can move the temps around but can not get all of them in a
safe operating
range. on the left side i got #2 down to 270 degrees but #4 went up to
340 plus. i put a longer dam at #4 and it came down to 285 BUT #6 went
to 353
even at low power settings. i have installed the dams - ground off an
1/8" at
a time - removed them and put them back at different angles. nothing i
do seems
to work. i can't help but think there is not enough air in the shallow
duct
to cool all three cylinders on one side. the right side 3 cylinders seem
to
be O.K.
has anyone had this problem and have you solved it ?? i know the prop is
coming
up on the left side and down on the right side so it changes the angle
of entering
air, but how do i get them all cool.
thanks for any help.
i have 85 hrs on it and still fighting CHT's
