Issues with a rebuilt 360

The reason why I never updated this again that day Was btw I’ll post pictures later but apparently the guy I recently gave my carburetor to broke two of the helicoils in the fuel bowl and the machine shop by me couldn’t really do much with it since according to them it’s special made and I can only get it from the manufacturer but when I called Demon they told me they don’t sell those so now I’m stuck looking for a new carburetor if any of you guys have any opinions on what would be a good carb please feel free
Holley 4150 Double Pumper Carburetors 0-4779S
Even tho the demon I had is almost the same besides this one having a choke was thinking about getting this Holley from what I’ve read on this forum it’s a very recommended brand
Edit: just to add on I saw the heli coil was messed up when I tried threading it in without the fuel bowls even on and it didn’t wanna go in then I looked and saw that one was both were pushed in a good amount
If you have to go new carburetor route I would recommend an Edelbrock from the AVS 2 line or something else that has annular boosters.
