Default LS6 CNC head flow chart

Dont know a whole lot about heads. found a set of CNC'd bare LS6 castings. this is the flow chart from them. the ports could use a little bit of polishing on them to help them out. Base on the chart, look like a good street head?

most cnc'd ls6 heads will be a good option. flow #'s are tough b/c they vary so much from bench to bench. lots of different ways to test them to show really high peak numbers. but it is a good way to get an idea for what you got.

If you can buy a head that flows that for $400 there will be alot of low 10 sec NA cars running around. I have to wave the B.S flag.
