Head flow / intake flow

I've done some head flow testing with and without an intake bolted on. Head flowed around 275 w/o int 240 with a China man single plane and 260 IIRC with an untouched Eddy Super Victor. These were Brodix SPEC heads for a SB Chevy. Flow tested a set of Dart BB Chevy heads in the 400 cfm range, bolted on a sheet metal intake virtually no loss.
