Hi all. I have a 2012 Elantra Limited with 1.8L that blew a head gasket. I bought head gasket set from m RockAuto along with a new set of head bolts. The bolts are FelPro brand but only 4 of the 10 fit. The other 6 bolts are too large in diameter to go down through the head and into the block. Autozone sells the exact same head bolt set for this engine. Has anyone ran into this issue before and if so where were the correct bolts found?
