With my first engine (Lyc 320), I built my own baffles from plans. Can't
remember where I got them, might have been from the Tony Bingeles book. I
did about 3 iterations starting with scrap .020 (easy to bend and shape) and
finishing off with .025 and .032 (in some places). Took about 3 months to
finish, so unless you have lots of time on your hands, not worth the
trouble.
With my new 360 engine, just bought the Van's baffles,... much, much easier
with just a little fitting and trimming. My new engine was a bit more
complicated because I have the ECI tapered fin cylinders, but they (ECI) had
a good template for that, too, so worked out fine.
I am one of the few here that advocate oil coolers on the rear baffle. I get
super oil cooling with mine. I used to always have to tape it up in front to
keep from over cooling, which is a real pain here on the west coast, where
in the summer you often fly over cool coastal areas or in the interior where
it is very hot.
So last year, I did a simple little trap door on the rear of the cooler
which is cockpit adjustable. Works perfect. In winter and over cooler areas
in the summer, have it mostly closed all the time. There is just enough
leakage, so that it still lets my temps get up to 180 in the winter. But
with just the push of a knob, I get great cooling, even during the hottest
summer weather.
The other benefit is that after initial start-up, I keep the trap door
closed, and it shortens my warm-up to get the oil temps up before take-off.

I never got any instructions with my vans baffle kit but it wasn't hard to
figure out where all the pieces went. A very good kit I recommend it. If you
really want to go from scratch I think there's patterns in the Tony
Bingellis book on engines.
