670 heads sound entertaining! I've always wondered what a max effort 350 build would be like (small chamber e-heads, etc), but I don't have the money and time to play with something like that. My driving and car use has changed, and has become more chill.

I'm running the 6X-4 heads on my 350/413 stroker with the Comp XE276HR cam. Lift is .502/.510 with 1.5 rockers. Ross flattops are set at 0.0 deck. No clearance issues and good for 453HP at 5600rpm and enough torque 442 at 4300rpm to tear up third gear in a TCI Streetfighter TH350.
