    Looking for LQ9 Heads Flow Numbers

    I have been looking every where for stock LQ9 flow numbers and also Ported LQ9 head flow numbers can anyone help... I know that the 317 are the same cast as the LS6 heads but with bigger Combustion chambers so do they flow different? I want to port and polish LQ9 heads for my 408 stroker but want them to flow crazy numbers is this even possiable???
