thinnest head gasket for 305

what can I use in my 305 that will give me a bit more compression and will be durable enough for garage queen street use.

its 30 over and I know I have seen head gaskets for 350 that are quite thin but I was not sure if I can use these on a 305.

Thanks

You can use them. The diameter will be slightly larger than the stock 305 gasket, but it won't make a significant difference. A thick 305 gasket will certainly be worse. Most aftermarket kits use the same gasket for 305 or 350, anyway.
