Well....thank you guys! I only posted those pics because that cutter is one I came up with that works really well on these heads...when I first started messing with them I did some flow testing with different angles and widths starting with a 2" valve and eventually settling on the 2.02 size. The extremely generous top cut + angle is what got me from the low 250's to the high 260's...on the unported version. Also, the generous back cut + angle is what allowed the heads to keep pulling up to .650 lift and only lose about 5 cfm from .650 to .700. This seat cut doesn't work on std. open chamber heads or Eddy heads though. Jesse, I look forward to the 5.9 results too....this project keeps taking small turns, in part to Johnny, so it's not quite what I wanted to do but I believe we will crest 450HP with it. Should be ready for dyno session next month if all goes well.
