I'm using a 50* seat on my street car, and I didn't do it without testing that particular VJ significantly. I also spent a large amount of time on the phone with my cam grinder before we settled on the lobes. Even on a head with a net lift of .600 (that is what I'm NETTING) I want to delay (or even reduce) flow below .250 lift.
While this my be counter intuitive to most, I have thoroughly flogged it out. Wish I had gone to the dyno, but I'm already way past giving a **** about the dyno for now. I'll see what it does at the track, and if it falls short of what I think it should run I'll pull the pig out and put it on the pump.
