Hey all. Thanks for all the info and advice. Tried re-torquing them, but still had the leak. Time to replace in now.

I would suggest using a Graphtite head gasket (I think that's the name). After installing a 5.5 head I couldn't get a good seal with the recommended gasket (the "modern style" with silicone around the water passages) or the stock copper one. Pulling the head with the modern gasket, I found that about half of it never adhered to the block or head... still looked new.

I heard about the graphite gasket, installed it following the instructions to the letter and it's been perfect. Don't quite understand why they say to use copper gasket spray on it but I'm not going to argue. No leaks inside or out.

Now the cracks in the block are the only things that leak...coolant
