I have been following this cyl head issue along with everyone else and have been waiting for someone to ask about left vs right cyl heads. Perhaps this has been talked about and I missed it. Do these engines have a different, as in not interchangable from right to left, cylinder head for each side?

Not sure but we all have the same number there.
Wendy I finally received the paper work here's a pic. You will notice my head serial ends in AC. Third revision??



And I also don't see the serial for the lifters tho it says at the top that they were replaced as well.

Also noticed RL at the beginning of it, Hmmm.

Yes not interchangable

Finally get some solid info and nothing?? Anyone?? Anyone??

As far as I know the exhaust manifolds are built into the heads so my guess would be they are not interchangeable.

Hi Detonator...

Thanks for letting me know about the AC part number. You are the first to report that part revision. And yes, I would consider that a 3rd revision, which is good for you!

I don't know what you say to everyone about all of the different numbers you are finding stamped on your heads, blocks, etc. My info is only coming from the part number that is on the invoice given to the people who have had their head(s) replaced.

Sorry, I leave much of this to the brilliant gearheads (33 and Roy) who know engines from top to bottom. And for those of you learning about these engines as you go though this process of discovery, keep up the good work.
