Highest flowing sbm heads?

Highest flowing small block MOpAR heads and someone has to bring this trash into the discussion. Great job.

After 20+ pages of derailment, the topic seemed to land at 700hp from a small block.

Engines are just air pumps. The attributes which made an honest 700+ from a 4" stroke and 4.1+ bore seemed relevant IMO.

The fact it took so much compression and a bore that's not possible with a stock Mopar block seems to rule out a stock block and pump gas.
