which brand throttle body to use?

right now i have a 2002 avalanche with a stck 5.3 , i will be ordering a brand new LQ-9, so i was going to buy a 80mm throttle body. i was thinking BBK. does anyone have any suggestions?

BBk should work fine.

use a ported stocker IMO.

I ported my stocker, too. but If I had a choice I would get a bbk.

fyi the inlet on your stock intake is 78mm. a quick search on tech got me this quote.

I'd use a ported stocker, or if you don't feel comfortable doing it yourself send it to mark at s2performance he does really good work.
