I have a 331 with AFR 185's and am willing to take some measurements for you but I think that you might want measurements from a 351 based car.

Interesting, I did not know that they had more than one header that lined up with the AFR heads.... Hmmm, well I have a 302 which would be the same block as you are using for the 331 isn't that correct? The measurement that I think would be the most critical would be the front to rear measurement of where the header connects to the side pipes at the flange. I guess we would also compare where the motor mounts are in relation to this to determine where the flange would end up. I am also concerned about the header clearing the foot box. Do you have any under the hood pictures of your setup.

Thanks, Mike
