Hi guys,
How can I tell if I have J heads on my 340? Or how can I tell what kind of heads I have? Thanks

if you look down by the lower head bolts by the #3 spark plug you will see a J or an O cast there , if you have the valve cover off it will have a casting #3 on the intake runner that should end in 915
