Yep, cut away... On my RV-4 and RV-10 you cut quite a bit of the
baffling away. In fact on the -10. There is only like 3/8" of
baffling left above the #1 and #2 cylinders when complete. Make sure
you have the air inlet scoops installed in the upper cowl too, or
there will be more cutting later.

Which comes first - the chicken or the egg?
You will have to cut a lot more than expected from the baffling.
Externally, the IO-360 and IO-390 are identical - according to Lycoming - so,
the
IO-360 baffling kit should fit. Consider getting some "Cowl Saver" silicone
rubber for the top of your baffles. It is super slick on one side and
will hold a better seal.
I can't say about the oil cooler because I remoted mine and it works great.

The RV-8's cowling done and fits like a glove. I started the baffling
last night
and its coming along nicely. The fit on the sides and back are very good
considering
the IO-390 installation (and the use of the IO-360 baffle kit). The
front baffling is completely different, however, and I'm slogging through
the
custom fitting.
But here's my question. I decided to put the top cowling on top of the
baffling
that I've got installed so far and I was shocked that the baffling appears
to
be a good 1 to 1.5" too tall!! Is this because of the IO-390 or is that
just
where Van's expects you to start in your "cutting-it-down-to-size" phase?
That's
a lot of snipping and fitting and snipping and fitting. I was expecting
to have to trim some, but not over a inch...
Also, it looks like the over-sized oil cooler is going to fit nicely on
the rear
baffle with only a little "modification". But I'm not sure if the back,
upper
corner is going to clear the cowling. Since the cowling is sitting over a
inch high right now, I've got no way to really trial fit the oil cooler
and check
for cowling clearance until I trim the baffling down. Worst-case I could
put a blister on the cowling for the rear, upper flange of the oil cooler,
I suppose,
but that's kind of hokey. There is room to move the oil cooler in towards
the centerline about 1", but then the mount will no longer line up with the
flange on the outboard edge and will require more modifications.

I just wanted to thank everyone for the great feedback on this baffling cut-down
procedure. I'm glad to hear that it wasn't just my installation!! :-)
I'll post some more pictures when I get things hacked down to size and that oil
cooler mounted.
