Question summit racing tb

hey dont know if i can post this but i think as long i keep it about tech it ok?
so they have an 80mm tb and an 85mm tb and it says they will both work but im not shure. i have an ls1 intake so i dident know if the 85mm would work.
the price is cheap and i know the quality is good because i have had summit brand parts before[they are about the same as big names like bbk and such i have had both] so just wondering if the 85mm will fit or go with the 80mm?
thanks

well i was looking at my year 1 catalog and they have a bbk 85 mm tb that they say works on a ls1 intake any one have a bbk tb? i might give them a call at bbk and see what they say.
will i have to change my bellows? its one of the ebay ones that has the 1 hump[lol]in it
maybe the inlet of the tb is 85 but the outlet is matched for the ls1/ls6 intake?
