I did say "plate", not block. It's common practice, if you have the right parts

Correct, I used a Quick Fuel plate, that has replaceable Holley jets, but fits inside the factory float bowl. So there is no metering BLOCK between the float bowl and main body. It is a direct replacement for the regular Holley 4160 metering plate, using the original screws.

If modifying the stock plates for Holley jets, 1/4-32 UNF, the jet needs to be shimmed out to give the fuel room to make the turn. Being an old toy airplane guy I use two glow plug washers per jet. I have forgotten what epoxy Gregg from Tri-City Competition recommended but it’s still in my plates after all the drums of fuel we have used.
