I am buying a L92 block with 60K to build for my C5. The heads are off the same block but the problem was that it dropped a intake valve and damaged the piston and chamber. So they just changed out the motor. The damage did not get into the valve seat at all.
So I need to know if it would be easier to buy a used set or fix the one damaged head and run them. They will not be ported just cleaned up.
