    Sorry sold...Professionall ported Yamaha 1.8L head complete with NA cams

    SOLD SOLD SOLD This is a professionally ported Yamaha 1.8L head suitable for a big boost motor. Head comes complete as shown in photo with NA cams. I originally commissioned this head for use on my "Shotime" GPR conversion build. Because of the issues I had with holding onto the motors for the build, the head was never finally put on a motor. It was run on the dyno once and has been sitting in a box ever since, I will attach that video along with some other photos in the next couple posts. I have also attached all the original invoices for all the valve work and porting work done as well as the flow numbers before and after porting. This does not obviously does not include the cost of the head and cams. The head comes complete as you see in the photos with a set of NA cams. As you can see I've got about $3200 just in parts and labor and porting not including the cost of the head and cams. I'm asking $2300 shipped in the US
