Default 5.3 heads from a '00 gmc, good??

I have access to new heads ordered for a '00 GMC Sierra Pickup with a 5.3 liter engine, code LM7. Are these the same heads that I keep seeing everyone talking about putting on the LS1? I'm assuming they can't be as this would be way too easy. Thanks.

Yes, they do need to ported. Those are some good cores though.
