I am looking at heads and I am curious as to what is the difference between
the M-6049-X303 and the M-6049-X306 ford racing heads.
they hae the same chamber and specs that I see, but one is $200 more then the other.

They make new pistons every day, so why worry?

If your looking to buy brand new aluminum heads, Check out Trick Flow twisted wedge heads, much more bang for your buck in my opinion.

In this case its an old set of GT-40's the 6049 in the part number means its a cylinder head. 6250 is camshafts. I don't think those heads are available anymore so the price difference is sales places are having to dump them
