Trying to determine if there is a left and right. Attached picture shows "R" along with a casting number. The two heads we have look identical.
Thanks!

906 head and no there isn't a left or right
They are the same and swapable. You could look for witness marks as to which one had the alternator bolted to it ( passenger side)
Great and thanks. The threaded hole for the alternator on one head is buggered up. Was hoping to switch sides. Engine is being rebuilt, so no issue with that.

Only after you bolt them on a block......
The head oils the rockers through the rear hole only. When you switch sides then the front holes that were never used are used and you need to make sure they are clean and clear.
Your photo shows the oil hole. Don't rely on your machine shop to do this, they may not.

Oh wow didn't know that. Thanks for the heads up. Luckily the heads were vatted and cleaned out. Both holes are clean and open.
