You can....but then you would have 8.5 to 1 compression ratio. Unless your running a blower/turbo you'd be backing up. As for headers its the same.

not if I get the heads milled to raise compression.

the 6.0 heads flow very similar (edit just searched,317 flows alittle more) to 241 heads but the 241 heads have 66.xx chambers v/s 71.xx for the 317s.
what heads do you have? imo you would be much better off with a set of stock 243 heads which i think have chambers around 64 cc or so.

well someone had a 6.0 w .030 milled heads and fast intake and cam w/ headers and mad 470rwhp so im trying to do something similar but on a LS1 block.

11:1 compression. The intake fit has nothing to do with the heads beings milled, they mill the heads on the chamber side, not the intake runner side.
