Both heads are the same.


Then pull a valve cover and get a casting number. I still say they are milled off on both heads.


Probably won't bother at this time. No matter what we need to come up with a rear bracket to mount the alternator anyway. Might worry about the casting number if the valve cover ever has to come off, but not until then.
