Convert to fuel injection instead of dumping your money into a crappy rebuilt Q-jet.

The fuel metering block may be warped.  Not an uncommon problem, generally the result of over-torqued fuel bowl screws.  New gaskets often hold for a few thermal cycles but then begin to bypass and leak.  If metering block warpage is the case, the block can be straightened in a press with careful application of pressure.  The blocks are soft and distort easily.  Fortunately, they also can be repaired fairly easily.
Good to know, thanks.  I ended up getting an Edelbrock 1906, but I'll take the Holley apart again and see if this was the case.  If it was, I'll fix it and at least get a few bucks for it.

Unfortunately, I couldn't afford to do that.

Spending $500 on a junk rebuilt Q-jet, you're more than half way there. You'll save in the long run. https://www.summitracing.com/parts/fif-30003?seid=srese1&gclid=EAIaIQobChMIvLydkbDz8wIVymtvBB2gBQ8TEAQYASABEgIRffD_BwE#recommended

WOW looks impressive! Does it meet California's smog requirement?

Funny thing they allow 300 ppm for these trucks!!!
