My 470 CFM Truck Avenger came with #57 fuel injectors, not enough for me to tune my carburetor. Totally useless purchase until I get a bigger carb which I may never have. The jets are good as always, so yes.
If you have a manifold the jets don't go deep enough for the main jet so it ended up being the right one Having to buy nozzle size (would have been nice to know when I ordered the kit, neither nozzle would have been what I needed) they fit a 99 nozzle.
