    if im not mistaking yes u will have to machine the heads for a 500 lift on the springs. but its easy and u can do it yourself. the tools are really cheap from jegs or summit.

    Comp makes LS1 style "beehive" springs that will support .500+ lifts and fit in the factory seats. I found this out about 2 days after I got my heads back from the machine shop (having the seats machined). If I had only read that article in Car Craft about 2 weeks earlier. :(
