Depends .... Do you need to pass emmisions? I run the emmision legal Edelbrock 60739 heads and was told by a tech at Ford Racing that they flow better the the Y303 head. You might want to look into AFR or TrickFlow. I know Trickflow makes an emmisions legal head that can us bigger valves (2.02) without risking piston to valve clearance problems.
