Texaholic, I have the headers currently plugged (those 3/8 npt ports that come out the side)and, at least initially, will not use manifold heat. I am using B model carbs with the rear having a manual choke (none on the front carb). If I was using the autochoke option for each, the tubing would connect to those cast in ports on the Fentons. Intuitively this all looks good, but it aint running yet neither. Stay tuned.
Good luck.
