This may seem like a dumb question ,, Chevy head markings, single hump, double hump, camel hump, spike,, where and how do I know what head I got or want to buy, need pictures or diagrams?? Does anybody know where to find such diagrams?

 

You might check out some of the performance magazine sites hit Hot Rod or HI Performance Chevy etc. What I do sometimes is look on the magazine aisle at the local supermarket for magazines that might have the information to see if they have a website or forum and then login there to see if i can find the answers to my question...
