Those look like short ribs from here. I cook mine with a little mesquite. I run my kettle at ~325-350. Season them up with some SPOG and maybe some worcestershire sauce, cook them til they have a nice bark on them, wrap in foil, continue til probe tender, and you are good to go. Last time I did these I think it ran about 4-4.5 hours.
