I finally got around to pulling the 440 partially apart that’s been sitting on my engine stand while I’ve been working on my 1940 1/2 ton.
Happily it appears the engine was professionally rebuilt and bored out, and has low miles on it since. I pulled the drivers side head off first, and changed the valve seals, gave them a quick lap and confirmed the valve guides are good, which they are.
I noticed on the bottom of the head there is a large R cast into it which made me think that it stands for Right. I haven’t removed the passenger side head yet which If they are sided would have an L.
It’s been a few years since I’ve worked on a big block; are the heads sided and marked L and R? If so I guess it means that means that when the engine was rebuilt they put the heads on backwards, since the one marked R is on the drivers side of the engine.
So my questions are, are the heads sided, and if so, what would be the issues with having them reversed?
