    cast iron heads to cast iron block, you can re use the bolts.
    aluminum heads to cast iron block, the bolts must be replaced.

    you have cast iron heads, so it is ok to re use.

    That is what I thought but, I bought new bolts and man you have to strech them petty far to get them tight.
