Hayabusa Cylinder Head - Ward Performance

[V8Pinto]

Selling my Ward Performance cylinder head for Gen II Hayabusa (2008 and up).  It is the 5 axis CNC ported one (stock valve sizes) and went 205MPH on my Busa last year at Speedweek.

It's got one Speedweek on it so maybe 10 runs.  Comes without cams.  Send me an email at Speedracer_1340@att.blackberry.net if you want pics.

$1,000 is where it starts and I'll kickdown Slim some cash from the sale.  Make me an offer.

Here's a link to the Ward page with the head.

Who did the testing and what size motor?

Bump to the top.  Head is still for sale.  Don't wait too long or the price will go up (or I'll build a big inch motor and use it).

Bump to the top - baby needs a new pair of shoes.  I'll knock the price down if you buy me a shirt from World Of Speed.
