i need to send the client this b"HTTP/1.0 200 OK\r\n\r\n" how

As an HTTP library, it's designed to abstract away the HTTP parts, so it's not really designed to send exact responses.

Without hacking things, the version comes from the request request.version, so if that's 1.0, then you should get the correct version. The status code defaults to 200, and you can explicitly set the reason (web.Response(reason="OK")).

Several default headers will be added though. A hacky way to ensure none are included may be to subclass Response and then replace _write_headers(), removing the headers from the last line: https://github.com/aio-libs/aiohttp/blob/master/aiohttp/web_response.py#L416
Or just doing:

    async def _write_headers(self) -> None:
        self._headers = {}
        await super()._write_headers()
