I asked a factory guy (Barry Shephard) about the costs associated with manufacturing heads for the 4.6 engine. His response floored me. Consider this: It takes 24 machining operations to produce a common (left & right side) GT-40 head for the 302. It takes 256 machining operations to produce a single side (left OR right) 4.6 two valve head. Even more for the 4 valve head. Now if you were an aftermarket company would you jump right into the fray?
