72 350 intake hot air passages blocked

[brown7373]

I am installing a crate 350 to re-place my original 350 that died. I will use my original intake and Q-jet. My intake center passage under the carb is filled, as is the center in my original heads which I am not going to use.

The new engine heads are NOT filled in the center. Will I have any issues if I install the intake with the passage filled on heads that are open there? I live in south Florida so getting the carb warmed up has never been an issue.
