Head Question YZ426

Hello All. Have been looking for a head for a 98 WR400 at a decent price for a while now and have found a head for a 2001 YZ426. Will this head fit the 400 motor and can I still use the 400 cams? Thanks A Lot.....sorry if this question has been answered recently.

Yes it will fit your motor, yes the cams will fit the head.

It will fit, but it won't have the port to connect your hot start hose to.

True, but the boss is cast into the head. You can drill it out and press in a nipple...

Great !! Thanks for the info.
