Default How do I identify the "113" heads..

I have to clean out the garage and was wondering what ID is on the aluminum heads from my 91' L98? I have heard about the "113" heads being desireable for porting. That seems like an awful large combustion chamber or an awful small intake valve. That about covers my old school knowledge for head identification.

I am guessing that the "113" refers to a casting number but want to be sure prior listing for sale.
