You are more than welcome. Now that is my personal remembrance of how it progressed. It may be flawed but even HEMMINGS TECH ARTICLES don't have it correct (IMO)

HOLLEY ran into EMISSIONS in the late sixties. That is why FORD went to the 4300 SERIES (designed by ROCHESTER) The H4180 was an attempt at an EMISSIONS COMPLIANT performance carb but FORD then went to CFI and MPFI.

I personally would have nothing but a HOLLEY unless just a street driver when I might use a 4100 or 4010. The original 4010 is still available from HOLLEY REMAN I believe.
