I have a cracked manifold on my passenger side i use the track just for towing most of the time (car to the tracks). I am wondering is headers worth putting on it or just replace the broken one with a stock one. thank you

 

Just replace it. Not worth putting headers for your application.

 

Mine was cracked in 2 places on my 92 F-150 4x4 with the 302. Not sure what motor you have but I took the passenger one off my 84 tbird with a 302 and it fit perfect. The stock pipe hooked up correct also. Just wanted to add that info. I don't think I would get headers unless you have the time and money. My brothers 81 F-150 with a 351W sounds awesome with full length headers though.

 

You can get a new replacement manifold on ebay. I don't know, but Orielly or Advance probably has them too. Thats what I would do.
