413 cylinder heads... are these toast??
Through this past experience I now look for cylinder heads that originally came with the hardened seats, so I don't need to replace them.
Usually just a quick touch with the valve seat grinder and put in brand new valves, then lap in the new valves at the end for a good seal.
For the needed valve guide work I do the Knurling then resizing process so that fits well with the new valves. Any milling, we have to send them in for that.
Kind of interesting and old time mopar dude was coming to the end of his run and donated all of his valve grinding and guide knurling tools to my mopar friend Brian. The guy wanted to see them get into good hands so they could continue to keep other mopars going into the future. The guy has past away now, but his dream and the tools still live on now though our hands.
The valve tools reside here at my shop now, and Brian has the Cam Bearing install tool that the guy donated too. Brian is the Cam Bearing install pro now.
Here are the 302 Closed Chamber heads that are on my '76 100 with the 318 in it. Heads came with the hardened seats and the valve guides were in great shape, just installed the new valves and new valve keepers and new single springs.
So Yeah, so far so good. Working out Nice . . .
