Highest flowing sbm heads?

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.
There is a member I know that is currently working on a better part of 800 hp stroked small block mopar. I was told it will be done late spring possibly early summer with the current parts delays. I will ask him to post up any details he would like to share after it is done and dyno'd.
