Heads will be complementing most likely a Tr224/224 112. I'm not all experienced in this area and undecided on which to get. AFR's?, Darts?, Patriots? LS1 or LS6 Heads? Could I just have my stockers ported? I mean what is really the difference in all of these.... flow numbers? If thats so than can't I just have my stockers ported to match some AFR's or it doesn't work that way? Thanks for any help!

 

Since in Calf. you might want heads that are CAFE legal,(AFRs) or maybe stock ported. I think with LS-6 heads you would have to update everything to that years standard.
