Default Few size limitation questions

Im building a lq4or9 based twin turbo motor. I currently have some 317 heads, and im wonder the size limitation of the bore vs the head. What bore size is a set of 317 good up to ? LOL im still new to this, so im just trying to get some detailed answers if anyone has some.

Originally i was thinking of doing a 370 build, but the more and more i think of it, i want to build a 408, but idk if the heads will be to small the the larger bore of the 408

317 heads come off of motors with 4" bores to start with. Besides you can put these heads on top any LS motor with no issues.

With the right pistons L92/LS3 heads will make more power and are pretty affordable too....

408 seems to be a popular choice in FI engines
if its dd ive been told its better to have more cubes
than boost if its going to be a dd car
more cubes ofcorse less boost
but more power.
