ALERT!! SOUND THE ALARM!!..

Ok, I got the wrong head stud kit too possibly... LOL. They sent me PC2459-1/2 and it listed a different part number??? But, I checked my 3 receipts and they didn't charge me for them, so if they are wrong I guess they are free... LOL
Did those turn out to be the wrong head studs? Because those are the same ones that I got...
