they're better than an ls1 intake...and they can be polished nice.
but the ls6 is just too proven of a performer for me to go with something else....unless it was the FAST.
trouble free for me. I haven't been to the track
since install, been a good while now. The mfr
showed a dyno matchup that says it beats the
LS6 somewhat, which it ought to given the
throat. You can port the aluminum some although
I did not (other than port-matching the heads
to the gasket; the intake dead-matched).
You'll probably hear some stuff about heat soak
but I don't think at the higher RPM there is enough
"time over target" to heat the air significantly.
On the flip side you could ice-bag it at the staging
lane for an actual (though still likely minor)
improvement over plastic, if it's that kind of a party.
There is also a ninety-some mm version. That would
be overkill for a stock- or mild-cam car I believe.

so to me....they pretty much make the same power.
so make your decision on other aspects.
looks, price, and whatever else you think is important.
the LS6 is proven....to me the bbk, typhoon, etc...are only speculated.
on my car i KNOW the FAST 90/90 gained me almost 20hp....same day same dyno tuned for each intake.
i can't say i've seen that for the ls6 to bbk swap yet.
