I don't know the mileage on the heads but the guy I got it from said "low mileage" whatever that may be... However judging by the injectors and intake of the motor, it must be fairly low as they are like brand new condition. The bottom end wrecked the block from throwing a rod but the heads are in great shape and all the chambers look great except that one chamber had some slight discoloration but doesn't look to be damaged. I will post some pics if I get time tomorrow. I work beside a machine shop as well so I can run it over there and get there opinion on it as well..

I looked the heads over and couldn't hardly find the chamber if it wasn't for the slight discoloration it had. No signs of any damage or anything. I took the heads to the machine shop next door and he looked them over and he said its from sitting and getting moisture in the one cylinder that threw the rod. He said no damage and head gasket sealed good with no signs of leaks or anything. He said he wouldn't be afraid to just clean them up and run them like that. I guess I'm just too **** over some stuff but just want the buyer to know what hes getting without any surprises... Anyways I uploaded some pics and a pic of the chamber to see the difference. Its the bottom chamber in the 2nd pic...

Does the intake have the fuel rail assembly? By any chance do you know if the intake and rails would be the same one as a 2002 Avalanche also with the 5.3?

Yes it has the fuel rail assembly. It has everything but the injectors. I'm not sure if they would be the same or not. Your injectors and throttle body might be the only differences.

I updated the pics of the heads. Heres an updated pic of one of the heads I cleaned up so people can better see what they look like. I only spent about 5 minutes on it with some carb cleaner and a light scrotch bright pad and look how well they cleaned up. These are nice heads besides needing a slight cleaning and they'd be ready to go.
