I just opened the po of the guides. Ya not good. Surprised he got them out as easily as what he did. what year are these engines? For some reason I recall GM doing something funky with guides on certain year heads etc. Still doesn't appear that really any water is going beyond the corroded erea. No trail or path of least resistance you can see.

the cast iron guides that were originally in the head have failed,using the bronze withe he salt water betw them and the cast iron is making a reaction,this will happen again.your best bet,,put cast iron sleeves back in.

1. Are the guides shown the original iron guides? Or replacement bronze?
2. Is it your opinion that the guides are causing the water corrosion on valves, or is it something else?
3. How can you tell compression is off? Gasket is mis-shaped?
