which header will fit ls/b18b1 ???

I have a 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 a nice header and just wanted to see if there was any difference between ls headers or type r replica headers or gsr headers. it seems like all the headers for sale i can find are for gsr or b18c5. thank you for the information.

any b-series header will fit.
