Pretty sure the heads are identical on the 3Y & 4Y.. Could be wrong but I'm 99% sure they are the same head!

Re: 3y head onto 4y???
stick with the 4y head as they have bigger valves and better flow. if from memory you can do it but the head gaskets are different,.
i wouldn't do it cos you are going backwards with valve sizing and flow.

Not wise to give a motor with almost no power, even less power
