Highest flowing sbm heads?

"Big ego, hurt feelings, n/a, turbo, gen 3 hemis, turtles", I think this thread has it all lol. To the op you can make allot more power with boost on a stock block and make it live when done correctly. I would not take a stock block and try the same power levels n/a, for me that's about 600ish and that's with a good sonic tested block. And all these guys "running fast on junk parts" with small blocks is not magic, as has been said over and over if you take the weight of the car and the mph most are around the 600 mark. Now ask how much time and/or money was invested to get the engine there. Unless you got allot of time/passion and skills it isn't the cheap and easy way to go, hell even most of the guys that can do it will tell you that, its mostly because the class rules dictate it.
