anyone know what jet sizes Racing beat runs / i should run in my new holley 465 CFM??? it is for a stock port with header

 

Stock Port RB Holley;
Model # R1848-1 =4160 @465CFM
Primary Main Jet =50
Secondary Plate =134-31 Stamped on Plate
Vacumn Secondary Spring Color =Plain

I have redone there setup for a StreetPort even after I sent the Carb back to them. I also upgraded to there Dual Feed Racing Bowl Goodie and really noticed a BIG improvement in Performance in all Ranges.
Let me know if you need the Spec's in How I Made A Racing Beat Holley Carburetor to work like it supposed to for what we Paid for$$$$.
