the standard ford firing order... if you numbered the cylinders like a chevy is the same.
except ford number 1 is passenger side and chevy number 1 is drivers side..
as for thinner carb spacers. there are several choices for 1/2 and 1" https://www.summitracing.com/search/part-type/carburetor-spacers?N=carburetor-mounting%3A2-barrel%2Bthickness-in%3A1-000_0-500&PageSize=25&SortBy=DisplayPrice&SortOrder=Ascending
but will an additional fraction of an inch be enough..
there are some 2" drop spun aluminum air cleaner housings that take 14" air cleaners.. you might have to bend the throttle linkage into a hockey stick shape but i think you have the lower throttle linkage..
PS... probably TMI. everything with a carb. and 5/16 fuel hose into the fuel pump inlet i use a 1994 ford probe 2.0L automatic trans fuel filter in the line before the pump.. 3/8 line i use a 1984 corvette fuel filter. this protects the fuel pump check valves from sediment and the carb needle and seat from seeping. causing stains on the intake and issues when trying to restart hot.. those two applications are 10 micron filters..
