This is the email i recieved from cosworth when inquiring for my top secret build

Hello Jon,

Thank you very much for your email regarding the Cosworth YB8069 Head.

Although, we do not have any YB heads in stock, we are currently reproducing the 2wd and 4wd heads. These will be available very early 2009. The big valve normally aspirated head will also be available early 2009.

I will keep you updated as to when they will be available. I have attached some information on our alloy YB block for your review.

Please contact me if I can be of any further assistance.

Best regards,

Ken Jacobs
