Re: Plugs for Vortec heads
I went through this last fall when I got new plugs for my Suburban. The original part number has been discontinued. There is a replacement number, but the material is different. I heard some people say that is fine, others that noticed issues. I believe in keeping spark plugs the same material as what they were from the factory. I went with the AC Delco 14. This is a platinum plug.
Now if you are running Vortec heads with an HEI, I would go with copper plugs.
