I'd love to have about .670 lift but the cam I have works well but most of all....it's the one I have.
The way I look at it the new heads flow at .420 what my old ones did at .550 so although I'm not pulling all I could out of them it should still work well and be pretty easy on the springs.
The Victor should work well enough to keep it fun. I really admire Lenny, very straight-up advice.
