This is the head from the 4-248. The heads are the same so I'm rebuilding both. This is just a quick how to remove the valve springs with a hammer and deep socket. The head will require some cleaning of rusty passages since the Exhaust pipe wasn't blocked from rain and snow. Its a simple procedure and can be done inhouse. Most times you would put a rag in the cumbustion chamber to keep the valves from going down with smack of the hammer but these valves are rust stuck so I didn't use a rag this time. When you put the valves back in you would definitely use the rag method for the valves. Most older engines can be done this way. Chev, Dodge or my favorite Ford can be done this way. I'm not sure about the newer engines but it might be worth a try. This is just my experience with valve spring removal and you can expect similar results with similar head setups. You could also do this method with the head still on the engine as long as you pressurize the cylinder. That would be another howto video that is probably already posted on Youtube. I'll be posting a video of inhouse valve spring installation when I'm ready to put this head back together.
