91-99 is a holley/ford "94" This has the jets inside horizontally at the front. Take big plugs out, undo with appropriately sized screwdriver (Might need grinding to go in). Jets should be 51s or 50s.

The jets that squirt from the top are accelerator pump jets and only work when opening the throttle. In steady state they are not squirting.

Having reread your original post I would swap back in the previous distributor and carb. They ran well before, they should do again. The fault was the cap.

That might be the simplest way of troubleshooting the new problem. The new problem was introduced when fixing the old problem, so undo what you did. Make the cap the only change.
