I tried searching this but could not find anything come up on this. So for anyone that has done the arp head stud remove / replace 1x1 method while the head is still on the block, is it really needed to drain your oil and coolant for two days or so prior to swapping out the head studs? I was recommended by someone lately to drain the fluids out of my engine so I wouldn't get any oil or coolant creeping into, or by the head gasket. I'm kinda like, why is this complicated? Half the people that do this method don't even clean the threads out before installing the new arp's 

Car ran consistant low 12's and never had a issue
