Ummm let me guess. The head was rebuilt for unleaded and had bronze
valve guides inserted?
If yes, the bronze valve guides are too tight and when they expand they
are siezing the valve.
Bronze expands more than steel so the factory clearences for valve guides
are too narrow for bronze guides. They should be reemed out a tad. I
don't know the dimension but I bet someone on the list does.
