any old holley would work for the bowl screws...theyre correct in fit and function, prob not to concerned with hardware, you cant see the bowl screws with the air cleaner on anyways

i have always had problems torquing the screws to the correct torque. I was enthralled when Holley went to hex head capscrews.

The stamped List & Chrysler part numbers on the reissues six-pack carbs represent original design specifications for their original applications only. They will contain minor Holley overall production changes that have occurred in the years since the original carbs went out of production as long as they don’t alter the design specs as they pertain to functionality. Holley went to hex head fuel bowl screws many years ago. More than likely to improve the process of setting even fuel bowl screw torque specifications on a mounted carb. It was a pain in the rear with slotted screw heads. Mine also had contained the newer gasket materials and the later blow-out resistant power valve. Date code should be reflective of the actual production date of the reissue. Carb pictured below was purchased new around ’07. Note the Torx headed screw securing the bowl vent lever rod, pretty sure that was a Phillips head screw originally.
Correct on all accounts. These are the differences that restoration minded owners need to be aware of when deciding on which way to go, buy new carbs or restore what they have, there are a bunch of small differences between vintage Holley's vs new when it comes to details, screws, misc. hardware, the Holley script on the bowls, plating and dip color, all kinds of stuff.

As for the bowl vent screw I've seen both Phillips and slotted Fillister head on original carbs.

John,only thing wrong with Holley is the price !! Out of these three sets,there were five bad bowl's,three had stripped needle /seat threads which I fixed,the other were Chevy bowls which I replaced,the two I bought from Chicago Corvette cost me less than $60. for both .
