So I was hoping for some advice. I purchased a pile of parts from a guy and included were a set of iron big block heads. I got them home and started checking them out. They have adjustable steel crane rockers and after checking casting numbers they turned out to be #2406518 64 Max Wedge heads. They are original and not the re-pops and from what I am finding they seem to be very desirable and very hard to find. So my question is should I have them gone threw and run them on my 440 for my Duster or are they valuable enough to sell and buy some trick flows? I like the idea of running them but if they are really that rare I am not sure. Thanks in advance.

Have them checked for cracks. Sell them to the guys that just have to have them. They are fairly valuable. Buy a good set of aluminum heads for yourself. Kim

The trick is finding an intake that will seal to the iron max heads.
The aftermarket max wedge port heads have a full panel between the ports for an aftermarket valley pan to seal against. The iron maxes are open in that area. Valley seal becomes a problem.
Just to make sure you have maxes (516s have been misread as 518s before) do these heads have a heat crossover in the middle? And 1.88 exhausts?

If they are stock/unported and the Valve seats
are not super sunk and shot, should be worth
an easy $2,500. Given they are original and not
the repop MP heads.
Sell them and buy aluminum heads unless you are
restoring a 64 Max Wedge car.

Also, in the old days, an untouched, UNPORTED max head was worth more than a ported set. Stock and super stock racers needed virgins. I don't know if that is still true.

There are only a very few guys that can use them, but there will be a few that can.
New Trick Flows would be a much better option in my opinion over these for the average guy.

The best of the best ( in vintage gear ) before the gen 2 hemi hit the tracks (and streets). I would not run them unless you have a very special project for them. If you do tho, an Indy intake for the 440-1s should work great for the strip. Vintage nascar single 4's can also be found $$$ to fit under the hood, or a crossram of course.
If they are repops, there will be a pentastar and an "M" in the casting.
Contradicting Tom, but i THOUGHT those are the first and only maxie heads for 6 bolt valve covers.

518 are 1964 Heads and all have 6 bolt.
286 are 1963/1962 heads and all have 4 bolt.
That is how my elder mind recall them.

518s are 6 bolt, you're thinking of the 286 heads.
