What cam?
IMO just mill the 317s and get a custom grind cam. Fresh vj helps too. No real need for other heads, since 317 flow just as well as 243/799

Yeah i figured that would be the best thing to do i know if i change the pistons to the flat top ls2 pistons the compression ratio would be fine with no milling required but thats extra cash and work to do....i hope the milling and good cam will do
