I have a GMC 6.0L engine.

It has a bad exhaust leak coming from the head to the exhaust manifold ( common problem i'm told ).

It has Aluminum Heads, and they tell me the bolts go bad.

The question i have: Is the 8.1L motor have the same issues ??
Does the 8.1 have Steel or Alum Heads ??

Has anybody experienced any problems with the 8.1 Engine ??

Thanks for any input.
