All Pushrods Bent and Wrong

Hey I’ve got a 74 gold duster with the 318 and I just pulled the intake off to deal with a dead lifter clacketing but I found some weird stuff. Here’s some pictures it looks like it has all the wrong pushrods excerpt one and they all are bent too then the lifters all looked wrong too not the same as the ones it’s supposed to have from what I have seen on the internet. How should I go about this I’m thinking just get all stick original parts?
