Hey Brad, I've been emailing you back an forth about doing a set for me but with Manley 2.00/1.55 stock size valves. I noticed this is a stage 2.5 and we talked about a stage 1. What is the difference-from what I can see it's just the valve sizes. Is there anyhting else that's different? Also what is the turnaround time? Talk to you tomorrow-thanks!
