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???

Take a look at these heads https://www.patriot-performance.com/...&cat=35&page=1. You might want to give Gunnar a call about porting your heads.

Stock L92 heads flow a little better than those PPs. For about a grand, you can get 'em built to accept .660" lift cams. I'm going that route with my LQ9.

But the L92 are square port and the stock L92 intake and SLP intake suck an choke the motor, Yea the heads flow amazing but know we are waiting on technology to catch up. My machine shop said fast is making an L92 Intake manifold. So, I guess we will see...
