ls swap header problems

ok i got my oil pan on, and im trying to get my header on. but the lower part of my header hits the oil pan right where the pipes bend, how did u b series swap guys handle this ?

or more of, what kind of header do u think it is because i know a ls header would fit, would a b16 header botl onto the block and clear the oil pan ?

Headers are almost always a problem to get on, how much does the header need to move in order to clear the oil pan? Is it a close fit, or does the header not even come close to clearing it?

Any B series header will fit a B series motor.

Is the header all put together, or are you trying to get the bottom half to mate with the top half?

im trying to mate the bottom half with the top half. i only need like maybe an inch, its really close

I usually have to wrestle with headers when we put them on, sometimes I have to heat things up with a torch in order to get them to fit. But an inch is quite a bit, and I seriously doubt that heating the header will make that much difference.

What kind of header is it? If its a Neuspeed one then I wonder if you got mine:iceslolan I ordered one from them and they sent me a 94-01 LS header.

actually its less than an inch but i cant be sure exactly. why the 94-00 ls header wont fit on yoru ls motor 91civichatch, or u dont even have a b series motor ?

no, i ordered a header for my ZC and got that sent to me for some reason. Oh well

did it fit ? do u still have it ? if it will bolt onto my ls and fit right, i might be willing to buy it from u, how much ?

Sorry, I just sold it on ebay for $230. It was in the classifieds section here for a week or two for I think $150 but got no bites so I resorted to ebay.

that sucks.

does anyone know if a 94-01 header will fit on my ls and fit right no problem, even bolt up to my exhaust ?

are you trying to attach the bottom section to the top section while the top section is bolted to the head? cause you almost certainly wont be able to that way. you should hang the top section on the studs, connect the bottom section, and then go back and tighten all the bolts

well normally i would try and do that, but since my ac fan is actually hitting my header and the header is all bolted down and everything. so i cant really take off the header that easy. but i guess ill have to try that. i dont really wanan have to dent my oil pan in or go buy another header. and yeah im trying to bolt the bottom to the top while hte top is all torqued down in place

sounds weird my header went on no problem.

what header did u use redman ? what year and stuff

at first i had the 95 integra header with the 90 civic dx downpipe, then i switched to a dc header, with no problems

ok i got a question about the dc header. does both peices say dc on it or just either the top or the bottom. i always thought the top part says it because ive seen it like that on other cars before. but i was examining my header and it says dc on the lower half, so im wondering if both pieces say dc, because my top piece doesnt

I have seen both ways.

The 94+ LS header will not bolt up to the 4th gen cat. The flange is rotated the opposite direction. If you dont mind getting some welding done, then go for it. In my case, I just ordered a test pipe to solve that problem. :D

mine says dc on the top only

i already have a test pipe
