This is a set of infamous 243 heads that were pulled from a running 5.3L LS4 Impala SS with 98,000 miles. These have been checked with a machinist straight edge and are straight. But you may still want a shop to take a look at them. They of course will need cleaned up and may benefit from a valve job. But they could probably be bolted on as is and run just fine. These have no broken bolts or any any other issue. This will also give you a boost in compression if you are swapping from 317’s on a 6.0l. If you have any questions please feel free to ask.
