Summit is always off the shelf expensive. Shops like DSC motorsports will build to your specs cheaper than Summit sells the off the shelf heads. As I said earlier, I paid about $1900 SHIPPED to Hawaii. you keep referring to "out of the box" performance. Since these are shipped with the 4v valves/already ported for that price, I would take a stand to say that these heads should be judged as "out of the box". Should be interesting to see what these modified eddy heads actually flow. I will contact Dennis Carrico to see if he has any flow numbers and post if he does.
