Just wondering if the valve sizes changed from head to head
Which head do you think would be best to use on the 3.9 EA block?
If I were to change heads I would buy the complete top end ( Head, manifold, fuel injection, ECU etc )
Which would be the best head performance wise? would it be difficult to install?
I have heard that the compound of alloy got progressively better through the range...is this correct?
any views most welcome
