You can purchase what is called "A Trick Kit" for your Holley that will allow you to "play" with it somewhat.
Having used Holleys so much in my over 50 years of car rebuilding, I learned quickly that you had better "double filter them". Those small metering ports get plugged up easily. I always kept a spare Holley ready to go.
