Rb26 head vs n1 rb26 head

[Bbyskyline]

Hey guys just a quick question. I recently bought an rb26 n1 head and was told that the only thing different between the head that came on the n1 block and the regular rb26 block is that the water galleries are a bit larger on the n1 head. So my question is, if this is true and if there is anything else different really!

Thanks

I don't believe there's such thing as an N1 head.

^+1 other than it was bolted to a N1 block from the factory.

All RB26 heads castings ever produced are identical. (same P/N, regardless what series of RB26). Internals such as cams vary between series.
