Do valve springs make a difference when putting in a solid flat cam. AFR says .550 max lift on their 1.45" 120# seat dual valve springs for a hydrolic. Do these limits apply to solid as well, or is it a different style spring. I want to go with a solid, but i dont feel like changing the springs for a few extra hp. And does .550 max lift mean that is the extreme limit or is that more of a buffer zone for them. I'm looking at a lunati vooddo cam(hydrolic) and the exhaust lift comes out to .560 with 1.6 rockers. Is that .010 over the limit gonna make a big deal. Thats like saying an elevator with a 1000 lbs max is gonna snap of the cables at 1002 lbs. Myabee i'm wrong.
