440 chassis headers, ( sort of )

These came with a roller race car I purchased on this site 2 years ago. Was told the car had a 440 -auto in it. There's a lot of slip joints and they are thick. Look at the pics closely.
NOTE - I've never installed these, I put a small block 4 speed in it.
There is another thread with tube measurements.
250.00 plus shipping, in cincy.
