wr400-yz426 combo? any suggestions?

I ended up with an 02 yz 426 with a blown top end and wonder what parts would work well for my 99wr 400, I'm a newbie and hate to say that I'm not too great of a mechanic. I'm slowly getting better with the help of TT.

Just about everything fits. The 02 has a different swingarm and longer shock though.

The 99 head will bolt right on the 02....the 02 has a larger rod big end so they cyl won't work w/o a custom piston.
