I do believe they are the same, but research for yourself on the web.
Go to Summit Racing's site, Jeg's, and/or Advanced Auto Parts. They all carry them, and allow you to order via internet.
Do some searching on the Summit and Jeg's and you will find them. I think they are the first part # that comes up on the list of Felpro headgaskets.
On the Advanced site you can just put in your type of car and see what head gaskets come up. This is also how you can research if a certain part (like the 8723 gaskets) is specific to TR's or is the same as a NA car, without going to the store itself and using there computers.
The Autozone site also has a setup like Advanced, but I dont remember seeing the 1000's. Although I dont see why they couldnt order them if you really wanted them to (probably have to ask at a store).
