you have to buy new ones because it's not recommended to re-use them..
so just buy the bolts to suit whichever engine you need them for , and your laughin'
i still would need to know if the headbolts are the same... 4efte engines aren't available here, i start a new job on monday and i can only get 5efe headbolts. So i need something quick.
i dont know about the head gaskets, i would imagine maybe the 4e are a little stronger? could have different oil pathways, but seeing as the head is the same i've ordered 5efe headbolts as they apparently measure the same length.
