headers for F body with 18* heads?

does anyone know if any header company makes a header for 18* heads in a F body? I have a 96 4th gen. I checked all the sites I could think of, Heddman, Hooker, Lemons, Stahl. thanks

Wouldn't that just be an LS1 header?

Okay. Just checking.

I figured that since the bore spacing is the same, LS1 headers might work on an LT1 equipped with 18-degree heads.

Nope, the bolt pattern is quite different

Lemons or Kooks. I found it cheaper to make my own. VM

Yep.... Lemons makes them.

They were about $800 uncoated back when this car was built, maybe 4 years ago.

Though you're right for the most part, there are always exceptions

Yeah, you can actually cut up and change the flange on a 23° header to get a 18° header. A better choice is a Kooks or Lemons.
