9 hous spent porting the second set of heads today and I still have some changes to make to the factory ported ones. I will be Deshrouding the valves in the combustion chamber on both heads and also changing the factory porting around the valve seats. I think there will be 30 hours or more into these heads.

You may be able to see how I have changed the shape of the seat/port compared to the factory porting job. Next on the list will be three angle cut on the seats. We do all our valve jobs the old fashion way by hand with Kwik Way cutters!
