Heads????
Reply #1 –
Just get a set of E-7 heads from a 5.0 EFI truck and call it a day.That's an upgrade from what you have,and cheap.The old 351 heads are good,but it's easier to get a set of GT40 heads.The EFI 5.8 heads are the E-7 heads like on the 5.0,but the holes for the head bolts are larger and you'd have to have inserts to use them on a 5.0 to make the the holes smaller for the 5.0 head bolts.
