I was wondering if this LS7 was going to have the same valve guide wear issues as past LS7's as well. If owners do have to send the heads off for new valve guides just to run a tune that will be crap. New Z28 owners shouldnt have to deal with those issues on this car especially since GM has known about the issue for 5+ years.
