Hi all, I have just pulled the heads off my 4.6, I think I can see the cause of my woes. You can see the fire rings and where they have been compromised. The water ways at the front and back of the block are fine, you can see the fire rings have not passed into them. A number of the other cylinders have had the fire rings compromised. And one of the cylinders has got a clean section on the piston, 2nd one back on the driver side. If I can, I will take some photos of the gaskets. So new block needed me thinks.
Anyone know a good place to get one from?
Cheers
