W/ a 3" lift or taller, ive searched and saw the LP30's in these years are prone to vibes after 3", and they also have the 0331 heads that crack w/ higher mileage. I'm trying to get first hand experience w/ any of this b/c 98 and 99 models w/ the HP30 and diff. head are far and few between in descent shape. Main question is this will be my daily driver, i'm lookin to spend no more than $6,000, preferably less than 100k on the clock, how many of you notice vibes after a 3" lift, and how likely is it that they ALL need head work due to the cracking 0331? Thanks for any info.
