Which heads to port. LS1, LS6, 6.0... I know an independent head porter and have a limited budget so AFRs are out of the question for a while. I want to go N/A. Which heads should I go with. From research, the 6.0s flow like the LS6s but have larger chambers so are better for FI. Why does it seem like everyone is going to 5.3s? I would think they have smaller ports and runners and valves. What is wrong with LS1 heads that people go with the 5.3s? Price doesn't seem to be a factor.
TIA

I think the reason people go with 5.3's is because of the 59cc chambers that allow you to get a jump in compression without milling and worrying about piston to valve clearance.
