Not Ranked
These heads are the best bang for the buck in FE heads. Other heads of inerest are the C0AE 352 HP units which also have the large ports, both of which are exactly the same ad the 1963-1965 427 lowrise heads which are now getting $$$.
Perhaps the highest evolution for the FE in conventional heads are Medium Rise heads. These are selling for $1,000 and more. Yes high rise heads are larger but ultimately your FE can't turn fast enough to use them effectively.
