I have a friend who is swapping an h23 into his accord after blowing his f22 motor. The h23 motor was bought without head studs in it or so I told him. He says they are called head bolts if they are oem and head studs if aftermarket. Is this true? I'm a pretty sure I am right on this one but I could be wrong and I figured I would ask you guys to figure out whats what. Isn't a head bolt a totally different bolt? and how many head studs are there in the h23 and f22?
