I think the Aux Venturis on all the Daytona Coupes are cut along with utilizing shorter stacks for hood clearance. This will change the signal strength and require a different jet package and probably a different Emulsion tube too. An engine of a given size utilizing a roller cam will generally be able to use a smaller fuel jet (all things being equal) because of faster valve opening events compared to a flat tappet cam. There are lots of variables when tuning these carburetors. More than one way to achieve the same results too.
