Deno uses hyper's default limits for headers size:

Max headers is 100 https://github.com/hyperium/hyper/blob/0eb1b6cf4d914ce9c3f8e92a8b43754eba27a327/src/proto/h1/role.rs#L31
Max buffer size is 800Kb. If the headers haven't finished by that limit, the response will be canceled. https://github.com/hyperium/hyper/blob/0eb1b6cf4d914ce9c3f8e92a8b43754eba27a327/src/proto/h1/io.rs#L23
