So if it is 1100 head and they put the 1100 cams in as well, im guessing it’s gonna like crap.

I have no idea lol i did also notice where the inlet rubbers bolt on the hole of the rubber don’t line up perfectly with the inlet holes of the head and came with 36mm carbs which I have just fully rebuilt and stage 3 jetted to now find I don’t have a dot head 

[Help identifying head]

Hi guys I’m having a bit of trouble with an engine that I was given for my project. The barrel says 748cc which makes it an 88/89 dot head but the clutch cover I think is off a 90/91 but the head is missing the casting dots so I’m guessing that the head has been swapped but I have no idea off of what.
