Default cooling line on back of heads

There is a coolant line on the back of the heads and when i took off my intake manifold to pull the heads to send them to lloyd elliot i noticed that the two washers (not sure if thats what there actually called) that seal between the head and bolt are in pretty bad shape. Where the heck do i buy these things! Its like a washer that has a silicone middle to not let coolant get by, help me find these please

they're gaskets. you can get them from GM. not sure on the part number but that's the coolent crossover. just ask for the gaskets. shouldn't be too expensive.

I haven't touched mine, but are they gaskets or are they like brake line washers, brass crush washers?

I just bought mine at summit, they were earls with a 1/2" opening IIRC. Didn't feel like getting raped by GM again.

I just did some head work, and had them replaced with oil drain gaskets Dorman part # 65269 they are metal around the ring and rubber in the center, youll need four of them and they're only about three dollars each, you can find them at your local parts store I got them at advance cause I work there
