If you keep asking people about the intake gasket on an LSx motor 99 and up (97 and 98 for the Vette and F-body) GM SBC ALL OF THEM, when they talk about coolant STOP. You are giving poor information.
Here is what they look like. Lifter valley covered, with knock sensors installed. No oil, no coolant. Every LSx. 4.8, 5.3, 5.7, 6.0, 6.2. 7.0 are like this. Iron or Aluminum Block. Corvette, Silverado, Sierra, G8, GTO, CTS-V, Imapla SS, Grand Prix GXP, Trans Am, Camaro Etc Etc.
The intake touches the heads and even has an air gap between the lifter valley and it's base. That is why the knock sensors sometimes fail. Moisture gets under the intake and corrodes the sensors.
Ok Rant off.
I'm glad to see your intake ports are as filty as mine on the 04 below with a K&N for ALL of those miles.
