My friend has a '93 LS and wants my stock B16A exhaust manifold on his LS, will it fit or not?

 

There's an 8.4mm difference in deck height between the B16 and LS, and I'm not sure about the difference of the oil pans. Has anyone done this? I want his header and he wants back to stock.

 

should fit. i got a b16 jasma header on my stock ls. fits perfect.

 

Thank you! Yeah, I've been reading around that the B16a manifold should fit, but that the angle of the flange isn't the same as a stock LS cat.

 

yeah, the cat flange mite be different. but you gotta try to know for sure. i had an ek hatch so it bolted rite onto my pipes, since the cat was apart of the header.

 

I have a B18a1 engine, and a stock b16 manifold (off an EM1 if that makes a difference). There is no clearance between the sock LS oil pan and the downpipe. I am looking for an LS header now; worried about oil temps and pan damage due to manifold vibration.

 

^^^ exactly.
