318, wrong rocker arms?

I'm 100% sure that 8 of my rockers are something that my 318 didn't originally have.

First pic showing the ones in the passenger side. Length: 76mm (2.99inch)
They fit well, and pushrods seems to go trough the center of the hole.
"93RT" or "93LT" stamped on them.

Second pic showing the drivers side. Length:84mm (3.3inch)
Just "T" stamped on them. I switched few as i was told to, but now the push rods are touching the head.

So what are these?
