Help w/ XS400 engine modifications

Anyone modify an XS400 for improved performance? Are cams available? Any OEM parts that are common? Does an XS500 engine fit?

Thinking valve job, and mill the head for a little more compression. Aftermarket Trumpet slip-ons, new jetting. Nothing crazy, just a little more power.

Thanks,

Never looked, but I would try the usual sites, megacycle, webcam, powroll etc.
There's bound to be something out there. Is that an 8 valve head like the 500?
