Ported 906 heads

I would not recommend running any factory iron head unless you feel like you just must run them 'cause you personally feel the need or your class rules require them.

Hopefully we have finished our last 906 heads for someone other than ourselves. With 2.14/1.81 valves these flowed 299cfm @ .550" and set the customer back $3,500.

We had the customer mail us a check for the full amount before we started the heads. You don't want someone backing out of the payment after you put that much work into the heads. And finding another person who needs/wants/can afford heads like that to sell them to is rare.
