Title says it all..........if so are there any HP gains to be had by using them?

i know the stainless manifolds dont flow as well as the later cast iron version.
im not sure on the year..... but one year is specific, gm part # anyway. prolly no difference from the others.

all 2001 and newer cast manfiolds i know are the same. they are not specific to z06. i ran a set on my stock cammed 6.0 and have been as fast as 7.17 1/8 mile with them.
i heard they flowed well, so i picked up a set to save on headers.
