Re: 5.3 casting number? whoever is doing your head work should be able to tell you. as long as the valve size, deck, combustion chamber and runner volume is the same, you should be alright.

Re: 5.3 casting number? The 862 and 706 are both 5.3 heads. If your wondering if you can use them as a pair the answer is yes, they will work as a pair, you just must use the old graphite style head gaskets.
