Fubar231 Posted July 22, 2012 Report Share Posted July 22, 2012 How do the 317 heads compare to the 243's? Also, how long did you run those heads with those springs? 918's are rated for .600" lift right? Im interested but i wanna do a little research first.

They are suppose to flow the same but 317's will lower your compression ratio hence while everyone uses them for turbo applications. The springs have probably 10k miles on them and yes are good to .600" Link to comment Share on other sites More sharing options...

I heard if you mill them .010 then itll be the same as the 243 heads. Link to comment Share on other sites More sharing options...
