(assuming you have access to a welder!)
thats the way i do it when the skid steer shears its hydro pump bolts, dont know if a manifold stud will take it??what if i were to give it a roasting with the oxy actylene first?[/quote]
localised heat will help, but be careful not to heat it too much, you might melt the aluminium cylinder head .
