Usually exhaust studs are removable and replaceable on any engine in any vehicle. I would avoid using a tap out on these aluminum heads so long as I could. Heavy 24 hour soaking of PB Blast, even though in theory everything is aluminum and shouldn't have rusted, studs probably are not,,vice grips and a hand held propane or map torch along with a sizeable dose of patience will usually do the trick.
