How old is the carb? Is it now rich at idle? The newer Holley's wont blow the PV on a backfire.
If you take it out the rubber diaphragm on it would be ruptured. You may have another issue which caused the backfire.
Now I need to pin those needles, got to feel that heat Hear my motor screamin while I'm tearin up the street

Yeah easy to check, being that new it should have the blow out protection, although I believe I've heard people claim it will still pop them, I've never had an issue.
Check your air bleeds for crud too. This a points car, or electronic ignition? Has it sat all winter? You'll know more when you get the primary bowl/metering block off.
