found a pic, the silicone heater hose I have did not come with the swedged end, so just bought a barbed fitting and use a small piece of hose at the firewall

I have a 2006 LS2, and when I bought a silicone hose set, I had the same issue.
I e-mailed a pic of the wrong hose, and they sent me a new one that fit properly at the heater core end. The lower heater core end ID is 3/4", not 5/8".
All other (3) fittings at the block and heater core were 5/8"
