Just wondering what heads would be best for 9.5 to 1 compression 351w. Heads must be stock production, with no sanding, porting, polishing, grinding, relieving, or chemical treatment to ports, or combustion chambers.
Can use ford gt 40 heads. Any thoughts or opinions? thanks

That is kinda what I was thinking too. What are the differences between the GT40's and the GT40p's?

The GT40p head has the spark plug relocated, and the exhaust face is machined on a different angle. Not all headers will clear the spark plugs. Have to drill these heads for 1/2" head bolts if there used on the 351W. Small valves but these heads work well.
