Just got a 350 for $100 bucks from a buddy at work for my 89 maro.. don't know much about whats in it.. looks like it was very well maintained, bearings all look new etc.. I was under the impression it was all stock. I pulled the valve covers and intake off and too my suprise it has a set of world products heads, roller rockers, and poly locks.. that's as far as I got with it tonight..
To the question.. how can I tell what heads they are?

 

Look for a casting number under the valve cover and email World, they can tell you. I did that with my 200cc Sportsmans, just to be sure.

 

thanks! I was hoping there was a way to look them up online

 

would you happen to know the email address or where I might find it?

 

http://www.worldcastings.com/catalog.../sbc_heads.pdf Probably easier than e-mail.... just find the number on the page
