| FE heads...a perspective |

Quick and dirty, I have a few flow #'s for comparison sake.
It was stated recently that ~35 year old ported factory iron MR heads flowed "only" 216CFM@500 lift on the exhaust side. Compare and judge.
Unported Ford MR 190CFM@.500
Unported Edelbrock FE #6006 190CFM@.500
Ported D0VE-C 174CFM@.500
Unported Victor JR Windsor 180CFM@.500
Ported 351C 2V heads w/1.71 valve 200CFM@.500
The best numbers I could find for 429CJ iron heads are
207@.800 lift,
There was one for 140@.600 also
Aluminum FRPP CJ heads, I found 262@.600
254@.800
Dove Std HR heads 222@.600
Dove Spl HR heads 250@.600
Dove Spl HR heads ported 300@.700
These may not be peak flows for all of these heads, but if you are only using a cam with .500 lift, what does lift at .800 matter?
Not many street/strip cars have cams over .600 lift?
I don't think that anything looks as cool as an FE. Anyone who is willing to spend the necessary money to build one can easily make a potent package. I don't think that anyone would think that they can take a set of C6AE-U or C8AE-H heads and go take on the world, but with carefully selected parts, a winning combination can be made.
