Help Cr125 head

I just got a 1993 cr125r for my 15yr old son for bday. It needs topend rebuild and the head looks pretty bad. I worked on many 2strokes when I was younger but it’s been about 20 years. Which is why I wanted an older bike. Anyway my question. Honda discontinued the heads for 93. I found a used head and cylinder for a 94. Im getting conflicting info if the head will fit. The cylinder is supposed to be the same. So can I put the 94 cylinder on his bike with the 94 head or can I just use the 94 head? I can probably get it machined but for the price of the 94 top end I wanted to use it if possible. I am new to this forum but been reading a lot on here and seems most know way more than me. Thanks for any help or suggestions

92 (*) - 97 cylinders/heads are interchangeable, just some slight porting differences. I would use the cylinder-head combo rather than just replacing the head.

*I believe the 90-91 were similar but used a domed piston so the head would be different.

I really appreciate the info. All my research says the cylinders are the same in those years but I’ve got conflicting info some saying the head won’t work. Looks identical but I wanted to ask someone who has experience. I’ll use the combo as you suggested. Thanks for your help and time

No problem .. the difference in the heads relates to the domed vs. flat top piston.

Oh Ok gotcha. Appreciate all your help. There is a pretty good chance I made need your expertise again before the build is over tho.
