i have a b20b in my ek and it needs headers the dc sport 4-1's are smashed on the bottom. i am looking on ebay and thinking of buying some 4-2-1 tri-y's and fabbing some plate to protect them from the street. my question is do b16/b18 headers fit the b20? i know they have more displacement but i am pretty sure it's due to the larger bore? correct me if i am wrong. i would hate for it to be due to a larger stroke and the headers not come down far enough in the "front" before bending to the back under the pan.
