I ran an old set of Brodix 10's about 20 yrs. ago and if i recall they flowed about .285 at .600 lift. Those heads require offset int. rockers.
I now have a set of the newer Brodix 10's they are spred port EX, and Raised port intake(1277 gaskets .120 tk), with 2.140 int. I also had to make 1/4" spacers between the top of the blk. and the bottom of the int. manifold. I don't have the flow charts on them and they flowed 308 @ .600 and 314 @ .700, they are setting on my 434" that's going into my Malibu.
hope this helps.
