IML: 440 sunken valves

["Robin Giesbrecht" <robings@xxxxxxxxxxx>]

Pulled the heads off of my 72 Imperial today. I have got several sunken 
exhaust valves which probably means the seats are gone.Could notice the 
different heights when the rocker arms were removed. Half the valve seals 
are useless.How do you get the drivers side exhaust manifold to clear the 
studs? Removing the engine mount bolts and jacking the engine makes things 
worse. Remove the engine mount and drop the engine? That is what I am 
thinking. Timing chain was trash but the nylon teeth were still on the 
sprocket at 105,000 miles. Very little carbon. This engine is stamped H 440 
with 1 and 24 under this. Any idea what this means besides the 440 
designation?
