Ive had a few burnt wires in my car too. The routing of the wires make it almost impossible to not singe one here and thereAre you trying to protect the wire's from the header's. They do make a heat sleeve that goes over wire's. Might be a better choice. We had that problem with the 440 in a drag car we had also. But those sleeves where not around back then.
Thanks 69bfan that was a big help, Big Mo.I have no clue on how Classic is identifying the #7 heat shields, but as you state, three different varieties. You can scroll down the page and view the different styles that Todd Hoffman provides for the restoration market place. His website does a good job describing the different styles.

Yes I know what you are talking about. I did order heat shields now but I still might get the sleeves for the plugs. Big Mo.Ive had a few burnt wires in my car too. The routing of the wires make it almost impossible to not singe one here and there
