backfiring during deceleration

I just put 83 motor back in car after repairing broken head studs and went for test drive. During downshifting or rapid decline in RPM's engine rapidly backfires. This does not occur during acceleration only during downshifting and not at idle.

Any suggestions or ideas would be appreciated.
Thanks
