Fell a tad shy of my 210 peak number goal, but close enough. The strong low/mid lift numbers will more than make up for that. These things stall at a lower lift than I hoped for. I was hoping they would flow to .450 hover to .500 then fall on their ***, but these things just don't have the cross section to hang on. The valve and seat profile I used also contributes to the early stalling, but adds to the low/mid lift numbers.

Won't win any bench racer dick swinging contests with these lol
