Windsor headers are available for the Pantera, but the dirty secret of
their design is that the pipes extend a significant distance to the side before
they turn down. On the right side, the rearmost pipe crashes right into
the water bottle! That means you have to relocate the water bottles as part
of the (many) modifications needed to cram a Windsor into a Pantera.

only need to buy one pair of heads. If you only have a dozen to choose from
instead of a hundred, so what? For sure you will find a pair that works
with your plans and budget, whichever way you go. Choosing Cleveland heads
is easier simply because there are fewer options, but there are still PLENTY
of options.

180 degree exhausts from Precision Proformance, so that's two. On the other
hand, there are numerous systems available for the 351C, so there the 351C
actually has an advantage.

>>>It's a matter of simplicity and parts availability. While there are
more engine parts available for the Windsor, there are fewer external
accessory parts available. So you would have to buy a bunch of external bits to
make it all work.
I used to be (for years and years) a huge proponent of switching to the
Windsor; at the time parts availability for the Cleveland wasn't good at all.
But the pendulum has swung the other way and now I'm a staunch Cleveland
advocate for the Pantera.
A determining factor may be whether or not you already have the external
bits for the Cleveland. If you don't already have the necessary dipstick
setup, pulleys, throttle cable bracket etc. and would have to buy everything no
matter what, that reduces the advantage of the Cleveland over the Windsor.
You can't go wrong either way, thankfully. :>)
