Equals will give you a few more hp but you wouldn't be able to feel the difference if you swaped unequals for equals.

Default RE: Difference between equal and unequal length headers

on equal length headers, great pains are taken to keep
every cylinder pipe the exact same length, so that each
cylinders exhaust as same distance to go. This keeps
the "exhaust pulses" in order and lowers back pressure
for more hp.

Shorties or unequal headers just take the shortest most
direct path regardless of exhaust flow.

If they are the headers he had last time I was up at his house the right side has some surface rust and the left is still pretty chrome.

equals are also more difficult to install, from what I've heard at least.

Default RE: Difference between equal and unequal length headers

i was debating that, originally gonna get shorty equals, but i ended up getting long tubes, either way i had to jack the motor up to install, but i like my long tubes better.
