Unless you are or have access to a competent machinist and equipment trying to do it yourself you will end up with a half assed job. We tried to do jets for carbs and pills for injection and they were never as good as the stuff u get from the manufacturers. Might work might not work worth a try. Fed 387

On the early vacuum carter bbd (68-73) there isn't a source for different jet sizes. At least nothing I've found online. I built a fixture and use a drill press.. It's not a perfect system but it gets the job done.. And it's free

I bought a nice jet drill set from S and K Speed back around 73, it has .038 to .110" bits. I use a very small battery powered slow speed drill and let the bit pull itself through, I use an old carb to hold the jet. The results are excellent as seen through a magnifying glass.

If you use Holley jets and they are too long, get some model air plane glow plug washers (soft copper) to space the jet. Glow plugs have 1/4 - 32 NF threads just like the Holley jets. Best source for the washers is the R/C flying field, just ask, most modelers have extras.

If you drill old jets try reaming them to final size with proper lubricant for the base material. This should help you get some repeatability on size. The better your set up the better the results.
