I thought this would help some guys out. Here is a link to help you identify some heads at a junkyard, without having to crawl up into engine bays and find casting numbers.

I figured it may help save some time for someone.

Too bad it deals with antique heads that are not worth the money to invest in. Late model and aftermarket heads are far superior to any of those old castings.

 

I just figured the chart might help someone out. Not all the heads noted are "antiques." I figured a few may be Third Gen relevant. I know it helped me identify my 416 heads on my 305, and maybe there are some old schoolers on this site, too, who may find it interesting.

It might help out guys who go to the junkyard, in search of heads, so they know a bit more quickly what NOT to pull off some engine. I figured, "what the heck."
