My home inspection of Speedmaster heads

Oh my goodness without a 19 angle valve job! What is this world coming to...
Don't forget to dress up those spark plug holes.... :poke:...
and I won't deny a 3 angle, or 5 angle valve job isn't better, but if the valves seal the heads will perform. Room for improvement? You bet! But walk around both my Dusters..... think there is room for improvement on the 2.76's/2.94's ? Stock converters?? low compression?? Small cams??? LOL.....
