1 step forward, 2 steps back

So I was trying to track down why there is any suction at all at the secondary part of the air horn. Took the carb off and I seemed to convince myself that there was some play in the secondary throttle valves when closed so presumably they could be sucked to open a little when the engine is running. Also felt like the primaries were hanging up a bit. So, I decided to fix that by pulling off the throttle valve plates to reinstall. Damn that red loctite works well, as I broke off 2 of the heads of the brass screws on the primary shaft :(

Trying to now drill them out, but I really don't have much in the way of precision machining/drilling capabilities.

If I can get them out, I think I may have to drill and tap from a 4-40 screw to a 6-32 screw. OR maybe I should just get another primary shaft. Are they really that expensive???
Looking on line for Corvette WCFB parts, a new primary shaft is >$140 but I don't know if they are interchangeable with our WCFBs.

Anyone have any leads on where to get a replacement that will work?

Just got her driving so bummer that there will be no driving for while :(
