Metering jet size

Anybody know the correct metering jet size for a 1962 4GC. I’m thinking it should be.065 main and .055 secondary. However the one’s on my carburetor are.080 and .065. I was thinking about it after I already put it back together and got it on the car. I’m pretty sure this is not correct and I know .080 is a pretty big metering jet could be why I’m having sooty exhaust and having the vehicle not run so good before I even did the rebuild. Anybody have any input on this?

WHICH 4GC? The one for a 394 uses very different jets than does the one for a 215.
