Hellcat PZ25 carb main jet sizing

Running all stock Hellcat. I know carb set lean from factory. Hoping to dial in better running mixture. I wanted to retain stock intake, air box configuration so purchased:

Installed and bogs at higher RPM. Hoping to change main jet and dial in this carburetor. Can someone comment on where to buy jets and sizes recommended? I'm at sea level. Top of jet is stamped with "74" or "14". Pic and dimensions below. Thanks.



Dimensions:
Overall Length=7mm
Head Diameter=5mm
Thread Diameter=4mm
