The bottom line is that it's a mute point these days unless you are restoring an original car and insist on original internals (not very common occurance) the stock stuff is basically obsolete. If you are building a 440 all you need is a good block and MAYBE a set of 906/915/452 iron heads (most go aluminum now) and a stock steel crank (I'd buy a stroker) and go aftermarket for everything else.
