Header recommendations for my 4x4 5 speed?

[BigB]

I got a 1990 350, that's a 5 speed and is 4x4. Looking to get a pair of headers that won't interfere with the fire wall and drive shaft for the front axel. I got a pair right now but the pipes coming off the flange are too fat to tighten the nuts, also flange is interfering with the sparkplugs making it unable to put them in. my old man bought them off some guy on Facebook, so there's a good chance they're not even meant for my truck. Would like long tubes, but probably wont work due to driveshaft.

Just get the ones for your truck.
