i need some advice. I,m looking to upgrade my valve train set up. I'm still running stock set up. Its a 30 over 440,10 1/2:1 ,292 purple shaft,727, 3:23 gear. The car runs low 12's now. Its a street car and i drive it everywhere. What brand do you guys recomomend? i would rather spend the money and buy the good stuff once. Thanks...joe
