I also paid $400.00 for a CNC option. I believe the flow figures above are for the stock heads, so they should flow a little better with the CNC option.

Only problem with one head is that the exhaust port has a thin line crack that you can't see. I was going to get this head fixed at the local shop, and they said 100.00 to fix the crack.

Since this happened, I came across a really good deal on another set of heads and decided to go with the other set. These heads have been sitting around for awhile and since times are tough here in MI, need to sell these. These heads are two years old and have less than 1500 miles on them.

Considering all reasonable offers.

Will post pictures soon.
