I would NOT trust the Daytona style inlet valves, i have lost track of how many carburetor these are nothing but flooding troubles regardless of fuel pressure.

For Tri-Powers i use only factory style and sized inlet valves, for 66 center .120", for 65 and older center carb .101". ALL end carbs .086". Never had a problem with factory style/sized inlet valves up to 6.5 psi.

FWIW
