I can tell you dynoing my friends 463 E head motor that made 640 HP with 2" headers we killed 40 hp swapping on my 1 3/4-1 7/8 Hedmans

Skip, was the header swap the only change? I know on my 463 with KRE heads I am giving up some hp with the 1&3/4" headers but I didn't think it would be in the 40 hp range.
Also on the carb issue I am running a QF 950 that I discovered is more than I need. Factory jetting was at 86/78. I am down to 82/74 and it is still rich, at least in warm/humid air. Will probably be pretty close when the cooler/drier fall air gets here.
