I'm going through the same thing with my small block right now. I hope you figure it out, and can help other's (me) to eventually solve this issue. I'm sure I'll figure it out eventually too, but I'd rather not tear the motor out or apart if I don't have to. It's pretty hard to drive it right now though. It ends up idling down to low in gear, and has almost no added boost for the power brakes. I'm sure that you must also be having brake issues?
