really isn't much to port on the ls6 intake.

you can't open them up to get inside.

i suppose you could open up the mouth a few mm...but not much.

in all reality...probably won't gain anything for the work.

stock with a ported stock TB is your best bet

I do not believe you can port LS6 without running the risk of ruining the seal area. Most people would probably jump up to the FAST 90 or now the 92.
