2008 YZ WR Heads

[wondermuscle]

Does anyone know if the YZ and WR heads are the same? The only differnece I can think of is the WR has an emmision connector that the YZ does not. Other than that....??

Their part numbers are different..... But does that matter?

YZ head - 2S2-11102-10-00

WR head - 5TJ-11101-10-00

Not certain, could be combustion chamber differences, but I believe you're correct.
