i had a 4-1 header on my b16a but then it blew now i'm uprading to an ls/vtec, the b16a 4-1 header doesnt fit because it hits the oilpan and wont allow it to come up any further for me to install the head studs.. is there a way to make it fit like using my b16a oilpan or do i have to sell it and buy another 4-1 header for another b series motor? TIA

 

you need any b18 (a/b or c) header in order to clear the height of the ls block. The jdm 4-1 is a good start
