small block chevy heads... casting marks

Im wondering if there is a page that has pictures of the different casting marks to tell me what they meen. i know what the hump heads and vortecs look like but i need to see th rest.

 

Some times they are decieving.
Casting numbers are better. look here for numbers.
If you get the "how to hotrod small block Chevrolets" book, it's got the symbols in it.
You "NEED" it anyway.
