will all b18 headers fot ls

i have ls swapped eg hatch. planning on all motor build non-vtec. just wanted to know which b18 headers would fit. i know the head bolt patterns are the same but what about oil pan difference. anything?? i would like to get nice header and just wanted to see if there was any difference between ls headers or type r replica headers. it seems like all the headers for sale i can find are for gsr or b18c5. thank you for the information.
