I agree with the warranty and all that but those warranties have one s*** ton of loopholes. I'll show you my invoice I paid $79 to have my cam reground for the second time because I wanted a different profile and$4 each to resurface my lifters. Again for the third time the same cam on its third profile is doing absolutely great! One thing I've learned in life there's no guarantees! again the suggestions I'm suggesting are 100% free even now in the after thought. Again my frustrations are for you not against you.
